The post base-pass dbuffer blending only works for simple and single materials. Complex material are still apply during the base pass. This pass is disabled by default, and will be enabled only per-platform. Following needs to happen making unpacking/packing modulare and reusable.
On lower-platform this allows to reduce significatly the cost of base pass (BasePass:-1.2ms DBufferPass+0.4ms = -0.8ms net), as the compiler can better prune code, and allows to increase occupancy.

The shader compiler will enable ISR or Mobile Multi-View in shaders, independent of whether they are actively engaged in stereo rendering.
But we _bind_ the instanced view UB when we think stereo is active. We can bind the instanced view UB even while doing mono rendering.

The previous control was just setting the D3D12 bindless heap sizes; now those sizes can be set and will only be used when the RHI controls are enabled.

- Adding support for bindless resources/samplers. The loose resources have to be wrapped in a macro that generates an index and proxy resource when bindless is enabled. Reflection has to parse these differently from other resources since they're parsed as uint parameters. The runtime also has to bind these differently since they end up needing to find their real resource in the binding data and then update a constant buffer.
- To assist in conversions, the shader compiler will detect if a shader is compiled with both bindless and non-bindless resources/samplers and will emit errors if that is the case.
- Adding support for bindless Uniform Buffer resources/samplers. Because Uniform Buffers aren't per-shader, they'll always update their constants with the bindless indices of their resources.
- Adding more flags to FShaderCodePackedResourceCounts required changing all the array initializations to individual parameters since not all the new flags are used everywhere.
- No shaders have been configured to support bindless resources/samplers. Yet.

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.
