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

- FileCache can dynamically allocate/release memory as needed
- Preloaded lines are locked in the cache. One the preloaded memory has been read, the line is unlocked. This prevents preloaded lines from being evicted before they're needed.
- Cache line size changed from 64k to 16k, reduce fragmentation due to locked preloaded lines

- Each shadermap is now associated with one or more assets, and shaders are laid out according to the
open order of those assets, if provided. If not provided, the original ordering is kept. The original ordering
will not be always deterministic, particularly if shader compilation needs to happen, because jobs can get
reordered during the compilation.
Other fixes:
- Fixed sorting within the shadermap not being deterministic (FCompareShaderPrimaryKey)
- Fixed Niagara shadermap duplicating Platform property and not initializing it properly.
- Removed (unused) support for Child shader libraries (would not be deterministic).
