Skip textureNumSamples tests on non-multisampled formats (#4191)

* Compat: Disable multisampling tests on integer formats

Discussed in gpuweb/gpuweb#5004
Landed in Compat proposal in gpuweb/gpuweb#5053

* Apply suggestions from code review

* Skip textureNumSamples tests on non-multisampled formats

Compat no longer supports multisampling with integer texture formats.
Skip tests which require multisampled formats.

* Update to new multisample format support method.
