LibWeb: Delete BlitCornerClipping display list command

Browse source 
Contrary to LibGfx, where corner clipping was implemented by sampling
and blitting pixels under corners into a temporary bitmap, Skia allows
us to simply apply a mask. As a result, we no longer need the
BlitCornerClipping command, which has become a no-op.

- SampleUnderCorners is renamed to AddRoundedRectClip
- The optimization that skipped unnecessary blit and sample commands has
  been removed. However, this should not result in a performance
  regression because Skia seems to perform mask rasterization lazily.
