Since the mesa state tracker can promote RGB texture formats to RGBA texture formats (among other formats) without exposing any of that information to a driver, it is more desirable to have the behaviour of `PIPE_CAP_RGB_OVERRIDE_DST_ALPHA_BLEND` be the default. This avoids rendering bugs where an application sets `DST_ALPHA` blending on a format where there is no alpha channel, that has been promoted to a format that actually has an alpha channel. The driver can instead rely on the common code in the state tracker to convert the blending parameter to one that reflects the limitations of the application requested format, as long as `PIPE_CAP_INDEP_BLEND_FUNC` is supported.
