[Libomptarget] Run GPU offloading tests using the new driver

[jhuber6]

Summary

This patch adds a new target to the tests to run using the new driver as
the method for generating offloading code.

Depends on D116541

[jhuber6]

Adding XFAIL to test.

You need to generalise / replace this function to avoid passing nvptx64-newDriver or similar as the triple

[jhuber6]

Addressing triple and adding test for static linking.

[jhuber6]

Add AMDGPU

[JonChesterfield]

Looks good. We can land this and revert with greater knowledge if the amdgpu buildbot fails on it.

Could drop the amdgcn-amd-amdhsa and nvptx64-nvidia-cuda lines in passing, I should have removed them previously. Or leave them and we'll remove the -newRTL ones instead of renaming them.

LG. We should drop this newRTL thing at some point.

Yeah, I'll soon make a patch that removes the old runtime.
