Use Arm64 runners to validate native bootstrapping and run test cases

Since the build system has been updated to allow native execution on
AArch64 when targeting Arm32, this commit improves the workflow
definitions by running the "host-arm" job on Arm64 runners to perform
validation.

As a result of these changes, the "host-arm" job no longer uses
"run-on-arch-action".
