[RFC] Normalizing our type naming conventions

[aleksanderkatan]

I see some potentially unintuitive names among our types. I think that we should consider coming up with more general rules on how we name the types of our resources.

The points of discussion:

• d.vec2f, d.v2f and d.Vec2.
  I currently see no ideal way of addressing this. Renaming v2f to vec2f would cause even more confusion. I think that we shouldn't use lowercase names for types. Renaming to Vec2fSchema and Vec2fInstance seems too explicit and long.

• Tgpu vs Wgsl vs <nothing>.
  We have TgpuBuffer, TgpuBindGropuLayout, TgpuFn, TgpuVar, WgslStruct, WgslArray, Ptr, Atomic, Vec2f. I think that we should get rid of the Wgsl prefix, but I am not sure where to put the line on what uses the Tgpu prefix.

• AnyWgslData, AnyLooseData, AnyData and BaseData.
  I think that it may be argued that d.v2f is more of a Data than d.Vec2f. We could rename Data to Schema, but I'm not sure if we could consider Ptr, Atomic or vertex formats to be data schemas.

Suggestions welcome.
