Greg Daniel 7bfc9139c6 Remove GrCaps isConfigTexturable.
This also makes the isTexturable that takes a color explicitly called
isFormatTexturableAndUploadable. A lot of the uses of isConfigTexturable
were changed to the Uploadable version of the check, even though this is
not where we want to land in the long run. In the long run the uploadability
will be checked via calls to supportedWritePixelsColorType and all the
isTexturable calls should purely be about texturing. However, until those
changes land we keep it safe and keep the same functionality that
isConfigTexturable had by checking uploadability as well.
