There were multiple copies of very similar logic that contained subtle inconsistencies. There is an upcoming need to add some extra information to the DDC key, so it makes sense to centralize the logic first.
Keep the publically exposed function SerializeUniformBufferInfo but mark is as deprecated to signal to any users of the old API that there is a better mechanism now that can save them some boilerplate.

- The function was not checking to see if the shader type in the pipeline was the same as the shader type we are asking for.

This should fully address UniformBufferLayout/UniformBuffer crashes that randomly happen during shader compiling in the Editor.

- Splitting symbol generation and shader "debug info" generation into two different cvars. This should now allow us to generate symbols post-packaging without generating different shader variants. This should also enable us to always generate symbols and still have the final deduplicated shader sizes.
- r.Shaders.Symbols is now the primary way to enable shader symbols for debugging.
- r.Shaders.GenerateSymbols can be enabled to always generate symbols without writing them to disk.
- r.Shaders.WriteSymbols can be used to force write symbols if they were previously generated.
- r.Shaders.ExtraData can be used to generate shader names for engine runtime systems to use.
- NotifyShaderCooked replaced with NotifyShaderCompiled, prep for upcoming non-cook symbol writing.
- PC DXC shader compiles should only generate debug info when requested, not all the time.
- PC FXC shader compiles should generate debug info when requested, not just when r.Shaders.Optimize is 0.

- Frozen memory images may have de-duplicated sections, where the same object is referenced multiple times; this means default destructors might be called multiple times, which is not supported in general
- Add a hook to allow custom behavior to destroy frozen objects that may hold references to external resources
- Within shader system, no need to run destructors, since all memory should be owned by the top-level memory image

- This is used to allow editor to load cooked materials/shader maps
- Remove UE_FORCE_64BIT_MEMORY_IMAGE_POINTERS, and instead always force memory image ptrs to be 64bits...this simplifies some code, and plan is to remove 32bit support at some point anyway
- Frozen memory image pointers only need 32bits for offset, which leaves another 32bits to stash a type identifier...this allows us to interpret that frozen data being referenced, even it's packed for a different platform

Add freezable hash table, use to accelerate lookup of shaders within ShaderMap
- Shaders are searched by TypeName and PermutationId, so move those fields out of FShader and into separate arrays inside ShaderMap, to reduce cache misses while finding shaders

Fix issues causing material DDC values to be non-determinisic
- Shader code within resources sorted by hash
- Debug source code values sorted by type
Also add mechanism to serialize any MemoryLayout described type to string
- Makes it easier to inspect material data to find sources of non-determinism
