Improve bookkeeping around formats. Hopefully make code less confusing. - Rename TlutFormat -> TLUTFormat to follow conventions. - Use enum classes to prevent using a Texture format where an EFB Copy format is expected or vice-versa. - Use common EFBCopyFormat names regardless of depth and YUV configurations.
