This moves the generic arm/arm64/x86 settings into the main makefiles
and makes the rest of them derivatives. This better aligns with how
soong handles arch/cpu variants.
Also updates the Android.bp to make it consistent with the make
versions.

Add an optimized memset that is ~20% faster for cortex-a7 and
cortex-a53.
Add a 32 bit optimized cortex-a53 memcpy that is about ~20% faster
on cached data.
Fix the cortex-a15 __str{cat,cpy}_chk.S, memcpy_base.S to remove
the phony functions, since they aren't needed any more. Then add
a direct include of these for cortex-a53.
Verified the new functions by stepping through all of the major
paths and verifying the backtrace is still correct.
