[Driver] Enhance usability by allowing more simplified known targets

[mdtoguchi]

We are adding short aliases for commonly used triples that are passed via the -fsycl-targets option here: #3984

This only covers the spir64 arch targets for device and AOT. We should enhance this by providing additional known documented aliases that can be used for other targets as well.

From @AGindinson : Could/should we extend the aliasing logic for the non-SPIR targets?
I realize that in general, after sycldevice removal the flow will already be quite convenient for users of these targets, e.g. -fsycl-targets=nvptx64-nvidia-nvcl. But maybe a documented default of Vendor/OS would make CLI even better.

Looks like this one has been resolved a while ago.
