aarch-arm64: Update tune files

arch-arm64 is the base tune file for aarch64.  Update this to allow the
system to work with both aarch32 and aarch64 (multilib).

arch-armv8 is for compatibility, it simply uses the base config for now.

feature-arm-thumb was updated, since aarch64 mode does NOT have thumb support.
We should only be processing warnings and additional arguments if thumb
support is enabled on the processor core.
