Remove SK_SUPPORT_LEGACY_HQ_DOWNSAMPLING
Switches Skia's software HQ downscaling algorithm from Mitchell to
mipmaps.
This is a good idea because
1) it aligns the results with Ganesh (which already uses
mipmaps for downscaling)
2) mipmaps are cheaper/more efficient (to produce and to cache)
3) yields (arguably) sharper results, particularly when scaling to
half size - which appears to be a common technique used for
Retina-ready pages.
