arch/arm: add an armv8.3a core

Browse source 
The armv8.3a generation is a cumulative extension to armv8.2a.

Since gcc correctly enables the appropriate extensions based on the core
name, we don't really need to introduce a separate config for armv8.3a,
and we can piggyback on armv8a.

This new core is AArch64 only.
