Leon Scroggins III 6ccd2cabaa Generate Android build targets for dm and nanobench 
Generate targets for dm and nanobench from ninja and add them to the
generated Android.bp file.

Remove nanobenchAndroid and SkAndroidSDKCanvas. These rely on HWUI
internals and are currently unused.

Update gyp file references to removed files, just in case.
