LibWeb: Add initial implementation of CRC2D.clip()

Browse source 
This allows clipping your drawing by any path you like! To do this
all painting has been wrapped around a new draw_clipped() helper
method, which handles the clipping before/after painting.

Note: This clipping is currently missing support for intersecting
clip paths.
