Currently, if all tests are skipped we print success, which is
misleading. Print a better message.

Previously, we always used "." to list tests in listTests. This patch
adds it as an argument to be used in a later patch.

This patch improves loading tests form a file.

First, it allows for having comments with lines starting with '#'.

Second, it lists the tests based on the provided user pattern instead of
using it as it is. Previously, the test name was defined by the user
pattern. This lead to inconsistent reporting. This patch fixes this
because now we report per-test results rather than per-pattern results.

It is possible that a test is a substring of another. Use a strict
pattern so that we execute only the specified test.

There are two ways to skip a test in our CI:
 1. add it to CiBlacklist in split-tetragon-gotests
 2. use t.Skip()

CI results report 1., but they do not report 2.

This means that skipped tests can go easily unnoticed.

To report tests skipped with (2), we need to parse the result files.
This patch does exactly that. It adds a new option
--enable-detailed-results. If this option is set, we set KeepAllLogs
because we need to parse all logs after the tests are finished.

The tests we skip with (1) are marked with ⏭️.
We introduce a new symbol for the tests that are skipped with (2): ⚡

Parsing the detailed results allows us to also report sub-tests (i.e.,
tests executed with t.Run()).
