apple: Meson defines GLX_USE_APPLE to allow for Gallium drivers to work on MacOS.

Browse Source 
By default, on MacOS, MESA will build a version that does not run the Gallium drivers on MacOS.
GLX_USE_APPLE must be defined to switch the code over to using the Gallium drivers.

GLX_USE_APPLE will be defined if any Gallium driver other than just SWRast is requested.
The default behaviour, due to default values, always asks for SWRast.
This logic leaves the default behaviour alone but allows the Gallium drivers to be actived without extra parameters.
