  [clang][modules] Determine if the SDK supports builtin modules independent of the target (#134005)

Whether the SDK supports builtin modules is a property of the SDK
itself, and really has nothing to do with the target. This was already
worked around for Mac Catalyst, but there are some other more esoteric
non-obvious target-to-sdk mappings that aren't handled. Have the SDK
parse its OS out of CanonicalName and use that instead of the target to
determine if builtin modules are supported.
