xen/multicall: Rework arch multicall handling
The x86 multicall handling was previously some very hairy inline assembly, and
is hard to follow and maintain.
Replace the existing do_multicall_call() with arch_do_multicall_call(). The
x86 side needs to handle both compat and non-compat calls, so pass the full
multicall state, rather than just the multicall_entry sub-structure.
On the ARM side, alter the prototype to match, but there is no resulting
functional change. On the x86 side, the implementation is now in plain C.
This allows the removal of both asm/multicall.h header files.
