builtins: expand out the AEABI function stubs
These actually may change calling conventions. We cannot simply provide
function aliases as the aliased function may have a different calling
convention. Provide a forwarding function instead to permit the
compiler to synthesize the calling convention adjustment thunk.
Remove the `ARM_EABI_FNALIAS` macro as that is not safe to use.
Resolves PR33030!
