Initial Rust CMSE support
Armv8-M and Armv8.1-M architecture profiles have an optional Security
Extension which provides a set of Security features.
This patch adds initial support of the Cortex-M Security Extensions but
providing support for the TT intrinsics and helper functions on top of
it in the newly added cmse module of this crate.
The code is a Rust idiomatic implementation of the C
requirements described in this document:
