Stop using GradientShaderCache for gradient textures

Ganesh uses GradientShaderCache for generating legacy gradient textures,
and a custom helper (initLinearBitmap) for all other cases.

Now that GradientShaderCache no longer supports dithering, there is
little difference between the two implementantions.  And sice the result
is also cached in a separate bitmap cache, we might as well consolidate
the implementation and always use initLinearBitmap.

This allows us to completely remove GradientShaderCache in a follow up.
