Move Ethos-U system validation, linker script preprocessing, and target configuration into ArmRunnerUtils so bare-metal runners can reuse the same setup.

This is the first commit of some that will create a sort of "stable" API for the cmake functions used by the arm backends. Just want to make sure things wont break with this.

Move Ethos-U system validation, linker script preprocessing, and
target configuration into ArmRunnerUtils so bare-metal runners can
reuse the same setup.
