Revert of Optimize GLES2DecoderImpl::ApplyDirtyState. (https://codereview.chromium.org/245923008/)

Reason for revert:
Failing compile on win64 debug waterfall bot

gpu\command_buffer\service\gles2_cmd_decoder_unittest.cc : fatalerror C1128: number of sections exceeded object file format limit : compile with /bigobj

Original issue's description:
> Optimize GLES2DecoderImpl::ApplyDirtyState.
> 
> ApplyDirtyState can on average 30% of the time of GLES2
> draw calls.  It previously set Color, Depth, Stencil masks
> and several enables without checking if they changed.
> 
> This change caches values used in ApplyDirtyState among
> other places, and adds ContextState methods for setting
> state with cache checks.
> 
> New cached state aware Set methods:
>  * ContextState::SetDeviceCapabilityState
>  * ContextState::SetDeviceColorMask
>  * ContextState::SetDeviceDepthMask
>  * ContextState::SetDeviceStencilMaskSeparate
> 
> Testing:
>  * gpu_unit tests now run both with cache on and off (ignore_cached_state_for_test = true)
>    to validate behavior independent of cache layering.
>  * New tests specific for caching behavior:
>  ** GLES2DecoderManualInitTest.ContextStateCapabilityCaching
>  ** GLES2DecoderManualInitTest.CachedColorMask
>  ** GLES2DecoderManualInitTest.CachedDepthMask
>  ** GLES2DecoderManualInitTest.CachedStencilMask
