Compat: fix float16(32)-renderable tests (validation)

[shrekshao]

Following #4148 fixing operation tests

This CL fixes validation tests

There are mainly 3 categories:

• Regular ones: add t.selectDeviceForRenderableColorFormatOrSkipTestCase(format); to require float16(32)-renderable features
  • For those requiring multisample support ,simply skip those as compat doesn't guarantee multiple support for rgba16float and *32float.
• (Example: maxColorAttachmentBytesPerSample.spec.ts): They aren't really testing float16, 32 format, they simply pick a random format to test storages, etc. Change them to another format (*uint) that still fits the need
  • Can't do that for createBindGroup.spec.ts, it's testing all usages: render_attachment, multisample, all 3 storage binding, there's no other format having full support of these like that of r32float.
• (Example: attachment_compatibility.spec.ts): They are testing if formatA === formatB. and the params.format is subcase. Simply skip 16float and 32float on these (regardless of float16(32)renderable availability). I think it's okay given what they are testing against.

Failing on core. I probably only test on compat skipping for this one... I will fix
