[shaders] Optimize the parameter metadata portion of DDC key construction. This is done by pre-computing a layout signature hash on initialization of each FShaderParameterMetadata struct and store it for use in DDC keys (rather than re-writing the layout to a memory buffer every time it's needed). This removes a massive amount of temporary allocations incurred by the unnecessarily complex FShaderSaveArchive mechanism, and has an outsized impact on editor startup time due to the usage of a portion of the DDC key string in constructing the unique name for materials (which is used in various places). In addition usage of the 32-bit LayoutHash has been removed from other places it was used in the shader DDC keys; this is a weak hash constructed by GetTypeHash which is not intended to be persisted. As part of this change the FShaderSaveArchive/SerializationHistory mechanism previously used here has been deprecated as this metadata hashing was the last place it was used.
