[MPS] Add support for output_channels > 2**16 in F.conv1d #140722
Description
🚀 The feature, motivation and pitch
#129207 discovered a silent correctness issue in conv1d with output channels > 65536. A guard with an error message was added in #129484.
On macOS 15.1 it looks like this has been fixed based on testing with the repro case from #129207.
Consider adding support for output channels > 2**16 again. Discover which macOS versions are supported and keep the guard for the macOS versions where it's not supported. Add unit tests with xfails for the versions where it is still failing.
