Describe the bug

AssertionHelpers.assertThrows() is a utility to verify that an exception is correctly thrown during test execution. However, during the development of #5138 it was discovered that test utilities trying to catch an AssertionError will not ever fail due to how assertThrows is implemented.

Steps To Reproduce

Create a test that always throws an AssertionError and wrap that in assertThrows.

Expected Behavior

assertThrows should allow catching any exception type.

…art of #5308: Fix a variety of dev platform-specific issues [Blocked: #5335] (#5138)

This PR fixes a variety of issues that were discovered while trying to
begin development on #4929 with a different workstation than I usually
build on.

Some of the issues were outright problems at the outset, but others were
discovered when trying to fix those issues (e.g. during test utility
upgrades).

Specific issues that were found and fixed:
- #5303: ``AssertionHelpers.assertThrows`` didn't handle cases when
trying to catch an ``AssertionError`` itself (such in the case of
``TestGitRepositoryTest``). This could result in false positives, and it
has since been fixed. Plus, the changes to ``AssertionHelpers`` also
removes the dependency on Kotlin reflection.
- #5304: ``LoggingIdentifierController`` could have ID generation
inconsistencies between environments due to how its ``Random`` instance
was initialized. This could also result in a test order issue if a
subset of tests were run, or run in a different order. The controller
has been updated to have better robustness against the order in which
IDs are generated which fixes the test and environment determinism
issues. \
\
The fix was essentially generating ID-specific seeds for ID-specific
randoms that all originate from the application seed, and are always
generated in the same order deterministically at the creation time of
the controller. This fixes the IDs being generated in different orders
leading to inconsistencies. Note that this is why ID changes are seen in
a variety of tests (since there are now new seeds being used for
generating these IDs as a by-product of the robustness improvements).
- #5305: ``model/src/main/proto/BUILD.bazel`` needed a fix due to a
build warning (that only occurs when trying to build all targets).
- #5306: ``TestGitRepository`` was made more robust by better managing
and setting the configured user & email used in its Git commands. The
utility now manages a locally set configuration for each rather than
relying on the global configuration (which may not be present on all
systems, hence the original issue). Some other improvements in error
detection were also added. Note that this likely wasn't discovered in CI
because it seems that GitHub CI _does_ set up a Git user & email
automatically, as do most people who work on the project.
- #5307 & #5308: ``ActivityTestRule`` is now deprecated in favor of
``ActivityScenarioRule`` since it can interact with activities outside
their lifecycle. However, the scenario rule is also not good to use
anymore since it can result in partial dependencies being initialized
before test-only platform parameter states can be overridden. This PR
introduces a new pattern to prevent using either of these rules, and the
mentioned issues can be used to track the remaining tests that need to
be cleaned up following this PR.
- #5309: ``ProfileAndDeviceIdFragmentTest`` is environment and
order-dependent due to out-of-order platform parameter initialization.
This issue ultimately arose from test parameters being initialized after
they're needed in the launched UI. It is necessary when there are
environment differences (e.g. local vs. CI) or when running certain
tests individually. This was fixed by removing the usage of
``ActivityScenarioRule`` and instead managing the fragment's test
activity lifecycle directly. \
\
Separately, the test performs proto comparisons that can be
machine-dependent. It seemed the test was suffering from some proto
encoding inconsistencies that seem to occur between some development
machines vs. on CI. The fix improves the test's robustness by extracting
the raw encoded string, verifying that the other outputs in the intent
message correctly correspond to that string, and that the string (as a
parsed proto) contains the correct values. As a result, the test no
longer depends on a hardcoded encoding value to be present for
verification. This does result in a slightly lengthier test with more
logic, but should be more stable in the long-term.

Some other miscellaneous notes:
- ``testCreateLearnerId_verifyCreatesCorrectRandomValue`` was removed
from ``LoggingIdentifierControllerTest`` because it wasn't actually
providing useful testing value. The application seed is not itself part
of the class's public API. Instead, the ID generation methods should be
ultimately verified.
- ``ComputeAffectedTestsTest`` had a shard increase to 24 and
``BazelClientTest`` has now been sharded to 4 (ditto for
``GenerateMavenDependenciesListTest`` and
``MavenDependenciesListCheckTest``). Both were done to help distribute
the more expensive tests in each suite across multiple runners to try
and reduce the long-tail of script test runs. More optimization will
probably be useful in the future. Note also that some of these tests are
*much* slower on certain systems (the one I've been working on, for
instance), hence the need for these adjustments.
-
``testEnsureNextResultIsSuccess_failureThenSuccess_notified_throwsException``
was removed from ``DataProviderTestMonitorTest`` since it *seems* that
it wasn't actually written correctly (and the issue wasn't discovered
until ``assertThrows`` was fixed). Per the existing test coverage, it
doesn't seem necessary to try and fix the test so it was instead
removed.
- ``ProfileAndDeviceIdFragmentTest`` changes led to a new
``EventLogSubject.hasNoProfileId`` being added.
- There are a few miscellaneous script infrastructure changes that were
pulled into this PR in preparation for downstream work. Specifically:
- ``ComputeAffectedTests`` now allows for its command executor to be
used for Bazel operations (which provides its tests with a bit more
execution flexibility). Its tests were also updated to use a longer
timeout for commands to try and improve test stability.
``BazelClientTest`` was similarly updated.
  - ``TestBazelWorkspace`` was updated to:
- Have better workspace initialization robustness (since the workspace
can actually be generated at several different points, not singularly
with a call to ``initEmptyWorkspace``).
- Add a ``.bazelrc`` file to disable bzlmod (since it causes network
stability issues in some environments when using newer Bazel versions
even if the project isn't upgraded, and we don't use bzlmod yet,
anyway).
- Add a ``.bazelversion`` file to ensure that tests are using the same
Bazel version as the project build.
- ``AuthenticationControllerTest`` was largely updated since the changes
to ``assertThrows`` behavior revealed that the failure test wasn't
actually correctly verifying an exception was being passed (since it
isn't actually being thrown; the test was a false positive possibly
because it was using ``Throwable``, but I didn't dig into exactly why it
was passing before). The changes ensure that the callbacks are actually
verified rather than the user result (since there's a separate test to
do that), as well as the exception's failure message.
