Michael Ludwig 3793335614 [graphite] Update Shape to use skgpu::Rect and float2
Switches Shape to store kRect types as skgpu::Rect instead of SkRect,
although it can be constructed or set from an SkRect. It returns a Rect
from rect() and bounds() now.

Also switches out the line to be constructed from float2's, and re-use
the fRect storage to store the first segment vertex in topLeft and
the second vertex in botRight.
