wined3d: Get rid of WINED3D_QUIRK_SET_TEXCOORD_W. 

This quirk only affects fixed-function fragment processing, which hasn't
been a supported configuration on the affected hardware for a while now.

/* The Intel GPUs on macOS set the .w register of texcoords to 0.0 by
* default, which causes problems with fixed-function fragment processing.
* Ideally this flag should be detected with a test shader and OpenGL
* feedback mode, but some OpenGL implementations (macOS ATI at least,
* probably all macOS ones) do not like vertex shaders in feedback mode
* and return an error, even though it should be valid according to the
* spec.
*
* We don't want to enable this on all cards, as it adds an extra
* instruction per texcoord used. This makes the shader slower and eats
* instruction slots which should be available to the Direct3D
* application.
*
* ATI Radeon HD 2xxx cards on macOS have the issue. Instead of checking
* for the buggy cards, blacklist all Radeon cards on macOS and whitelist
* the good ones. That way we're prepared for the future. If this
* workaround is activated on cards that do not need it, it won't break
* things, just affect performance negatively. */
