  [BOLT][AArch64] Fix crash for conditional tail calls (#140669)

When conditional tail call is located in old code while BOLT is
operating in lite mode, the call will require optional pending
relocation with a type that is currently not supported resulting in a
build-time crash.

Before a proper fix is implemented, ignore conditional tail calls for
relocation purposes and mark their target functions to be patched, i.e.
to be served as veneers/thunks.
