commit b59d160f62b04a5b83b7215ec2b84668b4db7a1b

Merge fast/masking into css3/masking

These two cover the same specification (CSS Masking), so merge the
smaller corpus into the larger one (also preferring non-fast over fast.)

The following tests are converted to testharness.js:

  css3/masking/clip-path-selection.html
  css3/masking/parsing-clip-path-shape.html
  css3/masking/parsing-mask-source-type.html
  css3/masking/parsing-mask.html

and additionally css3/masking/clip-path-selection.html is converted
away from using eventSender.
