libc: Consolidate unified definitions

Browse source 
As supporting architectures aside from AArch32 and AArch64 is not a
concern, keeping identical definitions in two places for a large part
of the libc seems counterproductive

The int128 types were left un-unified as __int128 is not supported by
gcc on AArch32
