8273153: Consolidate file_exists into os:file_exists

[elifaslan1]

This is not a clean backport. There was a merge conflict on os.cpp due to diverged os::split_path method for this reason os::file_exists method was manually added.
This backport is required to address a crash observed in Amazon production.

tier2 tests were run in addition to GHA
