arch: arm: Add initial support for Cortex-M55 Core

Browse source 
Add initial support for the Cortex-M55 Core which is an implementation
of the Armv8.1-M mainline architecture and includes support for the
M‑profile Vector Extension (MVE).

The support is based on the Cortex-M33 support that already exists in
Zephyr.
