Remove unnecessary `REQUIRES: x86-registered-target` from ps4/ps5 driver tests.

[MaggieYi]

Summary

Some PS4/PS45 tests include the line REQUIRES: x86-registered-target meaning they depend on having the X86 backend included in the build. This should not be necessary since the driver understands all triples regardless of which backends are included.

The change removes all unnecessary REQUIRES: x86-registered-target from ps4/ps5 driver tests.

LGTM. Checking the tests over by eye, it looks like all run the clang driver with -### or -E so only the driver itself is invoked, and no backend dependency exists.

Thanks Paul.
