Merge #189
189: Initial Rust CMSE support r=thejpster a=hug-dev
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: https://developer.arm.com/docs/ecm0359818/latest
Executed `assemble.sh` to generate the new static libraries containing the `TT*` instructions. Tested `check_blobs.sh` locally and it passed.
Tested on QEMU using the `mps2-an505` machine.
