[MINIHAL] Minor improvements (#7398)

* [FREELDR] Mark noreturn functions

* [FREELDR] Compile hw debugging support code only in debug builds

- Make BREAKPOINT() portable

* [FREELDR] Consolidate identical names into a single string

* [FREELDR] Use intrinsics for string I/O operations on x86 and x64

Stop them being pulled in from a static minihal library

* [MINIHAL] Exclude unnecessary portio dependency
