x86/retpoline: split retpoline compiler support into separate option

Keep the previous option as a way to signal generic retpoline support
regardless of the underlying compiler, while introducing a new
CC_HAS_INDIRECT_THUNK that signals whether the underlying compiler
supports retpoline.

No functional change intended.
