This MR adds a default implementation for `wglChoosePixelFormatARB` (in opengl32.dll) which will be used automatically if the driver populates the wgl_pixel_format ARB fields. Thus winex11 automatically uses this, and this MR removes the driver internal implementation.
The second part of this MR adds `WGL_ARB_pixel_format` support for winewayland (we can move this to a separate MR, but I wanted to have another implementation to better assess the behavior).
The `wglChoosePixelFormatARB` behavior is loosely modeled after the the AMD driver as discussed in https://gitlab.winehq.org/wine/wine/-/merge_requests/5388. I tried to keep things simple to begin with, and the results I am getting in various apps/games are sensible, but please try this out so we can refine further.
-- v2: winewayland: Support WGL_ARB_pixel_format_float. winewayland: Support WGL_ARB_pixel_format. winex11: Remove driver wglChoosePixelFormatARB implementation. opengl32: Add default implementation for wglChoosePixelFormatARB.
