Allow caller to specify if the want mip maps in makeTextureImage call.
Since Ganesh no longer will allocate mips late, this gives the clients a
way to tell skia that they want the texture they will be using to have mips.
It also supports allowing a client to take a non mipped texture backed
image and turn it into a new image which is mipped and texture backed.
