Update GrBitmapTextureMaker for handling mipped requests
Specifically this updates the case when we are requesting to use mip
maps but there is already an unmipped version in the cache. Previously
we just grabbed the unmipped.
Now we will create a new mipped resource. Upload the cpu data to all
the levels besides the base, copy the base level on GPU from the
original resource to the mipped one. Then the mipped resource will
take over the originals unique key.
