asm-generic: fncpy: Add function copying macros
Under certain arches (ARM) function pointers cannot be
used naively. Specifically, for thumb functions, their 0 bit
is set, but they are contained on a word aligned address.
Add a fncpy macro to perform function copies correctly
along with two helpers, fnptr_to_address, and fnptr_translate.
