Reland "Fix blurry edges on large ovals."
This is a reland of c7aed036c341eff661de2ccc3a728a9b68635159
Changes the precision for the GrOvalOpFactory shaders to be float rather than half.
In the medium-precision case, adds a scale factor to the shaders to ensure that the
denominator of the distance calculation stays within range. If enough precision isn't
available, falls back to a path renderer.
