Skip tests based on microarchitecture

Allow the TestHarness to skip tests based on micro architecture.

Ref: idaholab#25294, as it was determined ARM64 fails to run certain tests.
It may be best to skip these tests based on `machine` rather than
`installation_type`. Or perhaps we leave it alone for now.

Either way, this may become a useful feature in the TestHarness.

Closes idaholab#25317
