Do not allow render targets not explicitly written by the fragment shader to be modified (#3063)

Browse source 
* Do not allow render targets not explicitly written by the fragment shader to be modified

* Shader cache version bump

* Remove blank lines

* Avoid redundant color mask updates

* HostShaderCacheEntry can be null

* Avoid more redundant glColorMask calls

* nit: Mask -> Masks

* Fix currentComponentMask

* More efficient way to update _currentComponentMasks
