This unifies vertex and texture data formats
into a single base enum class.
`TextureFormat` and `VertexFormat` then mask
the invalid format for their respective usage.
Having a base enum allows casting between
`TextureFormat` and `VertexFormat` possible
(needed for Buffer Textures).
It also makes it easier to write and read data
to buffers/textures as each format will have an
associated host type.
These enum is generated from MACRO expansion.
This allow to centralize all information about
the formats in one place. This avoid duplicating
the list of enums for each backend.
This only creates the new enum. Porting older enums will
be done in other PRs.
Normalized integer CPU format are missing and waiting for #130640
