- 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.

Since the cbuffer uses the same name as the struct, we have to rename the cbuffer using a consistent prefix. The reflection handling also needs to reinterpret the renamed cbuffer as the correct UniformBuffer.

Migrating back to using UniformBuffer structs.
Since the cbuffer uses the same name as the struct, we have to rename the cbuffer using a consistent prefix. The reflection handling also needs to reinterpret the renamed cbuffer as the correct UniformBuffer.

The following code would call the int overload rather than the name overload when passed an EName constant, which could easily lead to confusion and bugs:
using FMyId = uint8;
void DoThing(FName);
void DoThing(FMyId);
DoThing(NAME_Actor);
The change to use enum class requires that any code that actually deals with EName as an int (mostly internal name code and serialisation) be updated to explicitly cast, but prevents the implicit conversion that causes the issue above.
In order to preserve the NAME_X aliases that the old-style enum added to the global scope, new aliases have been added that point to the EName scoped versions. Unfortunately these can cause shadowing warnings if NAME_X is defined in the local scope, as the old-style enum used to allow that without shadowing, however there is no way to prevent this so we'll just need to fix any warnings that occur.
