Add internal Format structure for texture formats

Browse Source 
Texture formats have plenty of properties we'd like to query on them
like their texel size, whether they are compressend or if they are depth
stencil. Instead of making switch statements for each of these
properties, we store them in a new `Format` structure. Textures compute
their format only onces and then pass a const reference to it on
GetFormat().

This is in preparation of adding all WebGPU texture formats.
