H5 with NSH support for Nucleo-H563ZI.

Made fixes to issues from CI. Nxstyle and defconfig syntax.

This is a combination of 6 commits.

Adding STM32H5 arch files. With comments addressed.

Created stm32h5 directory to add support for the H5 chip, and used a Nucleo-H563ZI dev board during development. The goal was to get a working nutshell through the STLink connector on the board.

Remove board/docs changes for PR update.

Squash commits into one for PR guideline conformity.
