fix(test): fix RNTester iOS unit and integration tests

[artus9033]

Summary:

This PR fixes problems with unit & integration tests in the iOS RNTester project, related to: compilation errors, JS problems, missing mocks & outdated baselines.

Changelog:

[GENERAL] [FIXED] - IntegrationTestsApp not registering components under proper names, breaking integration tests
[GENERAL] [FIXED] - IntegrationTestsApp flow types
[GENERAL] [FIXED] - Re-enabled iOS unit & integration tests, Ruby tests on CI, stripped obsolete build part before running tests, renamed uploaded xcresult artifacts
[GENERAL] [FIXED] - Fixed test_ios_rntester_dynamic_frameworks to respect the matrix flavor value, disabled running tests from that task to prevent artifact name conflicts since the test results for dynamic frameworks are uploaded from test_ios_rntester
[IOS] [FIXED] - Fixed Ruby scripting tests, refactored order of arguments to assert_equals where it was swapped
[IOS] [FIXED] - Reconfigured CI iOS test runner to run on iPhone 16, iOS 18.1, since the previous device was missing in the runner setup
[IOS] [FIXED] - Compilation errors of iOS unit tests
[IOS] [FIXED] - Fixed logic of broken iOS tests, add missing mocks
[IOS] [FIXED] - Disabled / skipped unit & integration tests that are coupled with legacy architecture bridge, which now throws upon initialization
[GENERAL] [FIXED] - Undefined symbols when building for testing due to missing CPP file in RCT-Folly.podspec

Test Plan:

1. iOS tests pass:

• When run from dedicated xcschemes:

• When run from the RNTester scheme (command + U):

2. Ruby scripting tests pass:

3. CI - green
4. xcresult artifacts are uploaded

Amazing job, I left a couple of comments.

We also have in CI a flag here and here that leverage these tests.

It would be nice if we can enable them to run in CI so we can keep them checked while we develop react native.

Can you update the PR with that?

[artus9033]

Absolutely, thanks for the comments, I'll address them today.

Great job! Unfortunately, there are a couple of issues that needs to be addressed!
