[CAS] Consolidate compile cache flags

Browse Source 
Rename `-enable-cas` to `-compile-cache-job` to align with clang option
names and promote that to a new driver only flag.

Few other additions to driver flag for caching behaviors:
* `-compile-cache-remarks`: now cache hit/miss remarks are guarded behind
  this flag
* `-compile-cache-skip`: skip replaying from the cache. Useful as a
  debugging tool to do the compilation using CAS inputs even the output
  is a hit from the cache.
