eric renaudhoude 8ae8e594fd Media: Fixed color space transformation on HDR Electra videos. ...

The (optional) display mastering color space (usually used as a hints for the display devices) was incorrectly used as the sample source color space. Since we are linearizing to the working color space by default, display HDR metadata can be ignored. We also take this opportunity to cleanup the media sample color space interface, especially now that FColorSpace is in engine core. Furthermore, tonemapping is applied by on Electra HDR videos so that their (unlit or composited) default appearance resembles other media players.

This change also introduces two news console variables:
* Electra.HDR.WhiteLevel
* Electra.HDR.ToneMapMethod

[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.
