[TEST] [OSS-ONLY] Implementing hashcode and mode based caching in 4X

[SiddharthBITS]

Description
This commit implements a more efficient method of caching compilations. Cache now restored will now be guaranteed to compatible with the version and build configuration of compilations.

We will now save 5-8 mins in version upgrade and dump restore tests.

Key changes:

Implemented new format for cache keys which includes github hashcode of corresponding engine branch and build mode to better identify the cache stored in a key.
New format "ccache-engineHashcode-buildMode-extensionHashcode".
Cache restoration handled by build-modified-postgres.yml and saving by save-ccache.yml composite actions.
Removed timeStamp based caching.
