Use Arm64 runners to validate native bootstrapping and run test cases

Since the build system has been updated to allow native execution on
Arm-hosted runners, 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".
