Greg Daniel 832c817bc8 Remove GrBackendFormat's textureType use from isFormatTexturable call.
The goal of this change was to remove the use of GrBackendFormat::textureType()
from GrCaps::isFormatTexturable call. Instead we will always pass in a
GrTextureType into this call.

To do this a lot of plumbing of GrTextureType was added to various call
sites. However, this CL halts the plubming up at the proxy level where we
get it from the GrBackendFormat still. Future CLs will continue removing
these call sites and others that use GrBackendFormat::textureType().
