Robert Phillips 6c70661f86 Pass GrMipMapped boolean down to GrResourceProvider::createTexture
This is the portion of:

https://skia-review.googlesource.com/c/skia/+/266916/ (Update two of GrResourceProvider's createTexture entry points)

I still care about.

Converting the boolean to an int and passing that down is dubious at best.
