Address mklement0 review: fix error terminology precision

- -ErrorAction Stop promotes to script-terminating, not statement-terminating
- $ErrorActionPreference applies to both non-terminating and
  statement-terminating errors (unlike -ErrorAction parameter)
- $ErrorActionPreference = 'Ignore' is now accepted (remove outdated caveat)
- Native command non-zero exit emits non-terminating NativeCommandExitException
