[iOS WK2] Fuzzy layers on sites using perspective and transforms
​https://bugs.webkit.org/show_bug.cgi?id=131873
<rdar://problem/16540576>

Reviewed by Sam Weinig.

Always set rasterizationScale on CALayers in the UI process
(as we do for WK1) so that layers are rasterized taking the
device scale into account. We can do unconditionally; this
is benign on layers that CA doesn't rasterize.
