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 Rel #130632 Pull Request: https://projects.blender.org/blender/blender/pulls/138069
