Fix: Allow creating view with usage=0 from transient texture

[beicause]

Found in gfx-rs/wgpu#9568. webgpu:api,validation,createView:texture_view_usage_of_multiple_usages:usage1=16;usage2=32 fails when viewUsage is 0 because isValid is false, but this should be valid because viewUsage=0 means full set of usage, because the view description.usage is resolved to texture.usage (https://gpuweb.github.io/gpuweb/#abstract-opdef-resolving-gputextureviewdescriptor-defaults).

Huh, how did I mess this up? Thought I verified all these tests against my Dawn fix...

Anyway this fixes the test in Chromium too. LGTM, thank you!
