Alternative fix for stale MIP maps on texture export/import.

This change assumes imported textures in SkImages have dirty mip levels
and disables regenerating the MIP levels on export (added in
https://skia.googlesource.com/skia/+/930f939c48af1be6005af12bb6f709ca5da9d118).

This is being done temporarily because it is a simpler change to cherry
pick to earlier branches than
https://skia.googlesource.com/skia/+/930f939c48af1be6005af12bb6f709ca5da9d118
