Refresh of disabled WGPU tests (#5614)

Some tests are now passing and are enabled.
Other tests are still failing, but are given comments categorizing the failures.

Tests in the 'Not supported in WGSL' category are also removed from the expected failures
list. (Though they are still kept disabled for WebGPU, of course.)

This closes #5519.
