Consolidate texture format lists for tests

[greggman]

Many tests take a list of texture formats. It would probably be good to consolidate those lists and or provide helpers/patterns for their usage.

For example. Some storage texture tests use TexelFormats in src/webgpu/shader/types.ts. Others use filter the list of all formats (kAllTextureFormats) by looking at kTextureFormatInfo[p.format].color?.storage === true or calling isTextureFormatUsableAsStorageFormat.

Ideally, a new texture format can be added to kTextureFormatInfo and would be picked up by all relevant tests? To do this, all tests should probably take some kind data from format_info.ts and call selectDeviceForTextureFormatOrSkipTestCase or other appropriate functions.
