Added support for additional Blend Modes

Created new BlendMode enum that maps to XferModes with additional
supported native values that map to SkBlendMode constants
Created new BlendModeColorFilter
Deprecated PorterDuffColorMode and PorterDuffColorFilter in
favor of BlendMode and BlendModeColorFilter.
Updated Paint API to use setBlendMode and deprecated setXfermode

Bug: 119671925
Bug: 112166079
Bug: 73224934
Test: Added CTS tests for BlendMode and BlendModeColorFilter
