jeannoe morissette a4b446428f VulkanRHI: Override ShaderParameterParser for Vulkan bindless resource declarations. Use a typedef for each resource's type and declare its variable array with that type, at the end (in SPIRV) collapse all the arrays of a same descriptor type on the same binding. Move 'per-stage' uniform buffer bindings into descriptor sets AFTER the descrciptor sets for the resource arrays (since the resource array bindings will never change, but the ubo will change at a very high frequency). Also add the possibility for platform common headers to overload UB_RESOURCE_MEMBER_RESOURCE to match the altered declaration in ShaderParameterParser (temporary solution). The result gets around the lack of ResourceDescriptorHeap in Vulkan. (Vulkan Bindless WIP) ...

Multiprocess editor support: Add the parameter -MultiprocessId=<N> to allow instances of the engine to have a unique id in their group of multiprocess instances.
