feat: Enable gmock and upgrade gtest to 1.13

[jeanmon]

We enable gmock from gtest. However, a compilation issue required to use version >= 1.13.
The latest version 1.14 leads to a compilation issue with the current gcc used in the CI job. It is apparently related to a gcc compiler issue (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105329)

No metrics with a significant change found.

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.

Values are compared against data from master at commit d566c747 and shown if the difference exceeds 1%.

LGTM but any more involved example of what we want this for?

Sure plenty will come. The single test change served only as canary to see if this is working as expected.

Now all the matchers can be used (which is the soul of GTest!) :)

https://google.github.io/googletest/reference/matchers.html
https://google.github.io/googletest/gmock_cook_book.html

They provide better checking and error messages (and readable expectations).

MAAANY thanks!

LGTM, but remember to use testing::ElementsAre in a followup :)

Reverted some test commits trying to fix report gates diff, but the one that stuck was adding INTERNAL to the cmake option here.
