Remove drawTextBlob from device use drawGlyphRunList

Convert all backends to use GlyphRunList instead of
text blobs. If the device did not originally implement
drawTextBlob it will be simulated by drawPosText on the
device.

Other changes:
Change to using an origin from absolulte positioning. The GPU
code uses origin change to update blobs under translation.

Change cluster to use const uint32_t instead of just
uint32_t.

Add SkPaint to runs.

The draw filter is hosted up to the canavas level and applied there.
