Update and enhance check_format_compatible.sh (#8651)

Summary:
The last few releases overlooked adding to this test. This
change fixes that.

This change also fixes the problem of older branches not understanding
ROCKSDB_NO_FBCODE and referencing compilers no longer supported.
During the test, build_detect_platform is patched to force no FBCODE
compiler usage. (We should not need to update old branches perpetually.)

Pull Request resolved: https://github.com/facebook/rocksdb/pull/8651

Test Plan: local run reproduces regression described in https://github.com/facebook/rocksdb/issues/8650
