Proxy canvas instead of DrawFilter for Android DM

Since SkDrawFilter has serious architectural issues and may be
deprecated, use a proxy SkCanvas for the same end: in every draw
call, inspect the paint, changing it to fit within the capabilities
of the Android Java (HWUI) drawing API.

Verified that this allows us to reenable all our ColorFilter tests.

dm/DMSrcSinkAndroid.cpp:35: typedef SkTLazy<SkPaint> SkLazyPaint;
don't see the need to typedef this for one instance.
