Use nine patch drawing for blurry round rectangles

Cherry pick of https://codereview.chromium.org/52703003/ in Skia.

Add SkRRect::transform.

Much like SkPath::transform, it transforms an SkRRect based on an
SkMatrix. Unlike SkPath::transform, it will fail for matrices that
contain perspective or skewing.

Add ability to ninepatch blurred rounded rectangle

Speed up drawing large blurry round rectangles by converting them to
nine patches.

SkDraw:
Add drawRRect.

SkBitmapDevice:
Call SkDraw::drawRRect instead of converting SkRRect to an SkPath.

SkMaskFilter/SkBlurMaskFilter:
Create a nine patch of a blurred round rect and draw it instead of
drawing the entire thing.

SkPDFDevice:
Override drawRRect to perform the old behavior in
SkBitmapDevice::drawRect.
