dan elksnitis 5bcff15345 [shaders] modify FShaderCode finalize to create a FSharedBuffer object, and modify all downstream uses of shader code to re-use this buffer (job cache, pushes to DDC, shader maps, and shader library). This reduces total amount of LLM tracked memory allocated at the end of a cold Lyra PS4 cook by about ~350MB; impact likely much larger for cooks of larger projects. ...

resubmit with following fixes:
- static analysis error which caught an >=0 check on a uint64 which should have been >0
- fix for an inverted guard on multiprocess cook sending bytecode to director (was only sending code across if empty instead of non-empty)
- fix for uninitialized padding in the FShaderCodeResource::FHeader struct causing nondeterministic puts
- fix for incorrect size passed to job cache hashing on receiving buffers from DDC
