This replaces the various implementations of memset and memcpy, including the ARM RTABI ones (__aeabi_mem[set|clr]_[|4|8]) with a single C implementation for each. The ones we have are either not very sophisticated (ARM), or they are too sophisticated (memcpy() on AARCH64, which may perform unaligned accesses) or already coded in C (memset on AArch64). The Tianocore codebase mandates the explicit use of its SetMem() and CopyMem() equivalents, of which various implementations exist for use in different contexts (PEI, DXE). Few compiler generated references to these functions should remain, and so our implementations in this BASE library should be small and usable with the MMU off. So replace them with a simple C implementation that builds correctly on GCC/AARCH64, CLANG/AARCH64, GCC/ARM, CLANG/ARM and RVCT/ARM.
