[Backout] - CL22476756
[FYI] tim.doerries
Original CL Desc
-----------------------------------------------------------------
Added support for filtered virtual shadow maps on SingleLayerWater. Implemented by applying the VSM shadow mask to the SeparateMainDirLight texture that is written out by the main water pass in the presence of distance field shadows (or VSM filtering) and then later composing it back into the scene. Also removed EncodeLightAttenuationFromMask() function from VirtualShadowMapMaskBitsCommon.ush.

r.Mobile.ShadingModelsMask can be used to mask out specific shading models on mobile platforms.
Masked shading models will fallback to DefaultLit

- Saves ~0.3ms on PS4/XB1 (Dynres = 100%).
-Add possibility to disable grass velocity output when WPO velocity is enable (only effective when r.velocity.enablevertexdeformation != 0 and r.OptimizedWPO = true)

This resubmits the following original changelists (with fixes).
Original CL Desc for CL20737284 -----------------------------------------------------------------
Add a version of UseVirtualTexturing() that takes a shader platform.
A future goal is to deprecate the version that takes a feature level.
Original CL Desc for CL20738687 -----------------------------------------------------------------
Virtual texturing forces depth pass on.
This fixes bug when using any masked materials that sample VT.

2.Uses the same shading models and dynamic lightings code path on desktop.
3.Remove the division of PI on mobile directional light's color in C++ to line up with desktop in shaders.

Local light shadows are supported on mobile forward and deferred, need to enable full depth prepass to generate the ShadowMaskTexture.
Remove the 4 maximum local lights limitation on mobile forward.
Remove the "High Quality Reflection" on mobile forward.
Disable simple lights on mobile forward.

Storing water in gbuffer and runnign extra lighting pass would be too expenssiv. So instead, when in deferred, single layer water always output the main dir light luminance into a separate 111110 texture.
DF shadow is applied on that texture. DFShadow culling step is cached the first time for a given view in order to be able to reapply DFShadow later with a depth buffer containing water. This save 0.4ms on a base console.
DFShadow is naturaly skipped if the directional light does not have that feature enabled.
When DFShadow is executed, it is basically 0.24ms extra on a base console @ 1080p.
The separated light buffer is an extra 8MB allocated when in deferred.
This only works with deferred for now (forward does not run the reflection/composite pass).
Render target slot assignement is a bit fuzzy but this is a mostly static setup so should be fine. And could change with Strata down the line.
r.Water.SingleLayer.ShaderSupportDistanceFieldShadow is to enabled dfshadow on water for the shaders. Defaults to 1 and will only be enalbed when using deferred and when distance fields are enabled.
r.Water.SingleLayer.DistanceFieldShadow is a runtime toggle of the feature (if enabled the shaders still output to the separate light render target, but that is simply discarded).
Follow up: tile upsample, tile traceshadow, make it work with strata.
Tested shooter and console.
