BUILD-8957

Refer to the local checkout to use other actions from the same repository, instead of a hardcoded reference to master.
There is no available environment variable to refer the proper hash, while the code has been checkouted with the proper hash.
A symlink is used because GitHub Actions rejects .. relative path in the uses: field.

🤖 Pull Request summary

Refactors GitHub Actions to use local symlinks instead of remote references.

• Action dependencies: Replaced remote SonarSource/ci-github-actions/*@master calls with local symlinked actions in .actions/ directory
• Build consolidation: Combined separate build tool setup steps into the main parameter setting step for cleaner workflow structure
• Cache key standardization: Updated cache key formats to use consistent cache-${{ runner.os }}- prefix pattern
• Restore keys simplification: Removed multiline restore-keys syntax in favor of single-line format

Review focus: Verify that the symlink creation logic correctly points to existing action directories and that the new local action references work across all build environments.
