Add test and benchmarks Timeout Guards [MOD-7846]

[dor-forer]

Describe the changes in the pull request

1. Added new TimeoutGuard class that receives a timeout on creation, and starts a thread that waits on a condition variable until the test is finished (changes the flag on destruction) or the timeout is reached.
2. Created a new main function that uses Google tests' TestEventListeners mechanism to start TimeoutTestListener (that uses TimeoutGuard), for every test.
3. Creates SetUp and TearDown functions (Which are inherited from benchmark::Fixture) in BM_VecSimGeneral to create and destroy the timeout when a benchmark is finished.
4. Disable the TimeoutGuard for EXPECT_EXIT test because they don't work well with the background threading, and added the TimeoutGuard manually to the test.

Pull Request Overview

This PR introduces timeout protection mechanisms for both unit tests and benchmarks to prevent indefinite hangs and improve CI reliability. The implementation uses RAII-style timeout guards that monitor test/benchmark execution and forcefully terminate if timeouts are reached.

Key changes:

• Added TimeoutGuard class for general timeout protection with configurable actions
• Created TimeoutTestListener for Google Test integration with automatic per-test timeout
• Integrated timeout guards into benchmark fixtures using SetUp/TearDown methods

Documentation inaccuracy: The comment states tests timeout after 30 seconds, but the code sets a 100-second timeout on line 23. Update the comment to reflect the actual timeout value.

Suggested change

	* Tests will automatically timeout after 30 seconds (or customized duration based on test type).
	* Tests will automatically timeout after 100 seconds (or customized duration based on test type).
