Changed ShaderArchive, GlobalShaderCache, ShaderDebugInfo and Autogen to use ShaderPlatformName and not ShaderFormat when naming their output files.

- Provides about 8% runtime memory savings (in local tests).
- Also, adds more compression types for shaders.
- Impact on the shader compilation (in SCWs) seems to be negligible in local tests.

Local shader compiler:
- Not making 1 job batches (for High prio jobs) on startup
- Randomizing pending job selection to reduce chance that multiple 60+ sec jobs get into a single batch
(the above have the most effect on speed up, below is optional/misc)
- Pushing the completed jobs back to manager before, and not after, pulling new ones to reduce idle time
- Processing jobs in FIFO rather than LIFO order (change to LIFO seems like an ODSC regression? Hard to say definitively if it's a regression from the numbers, but seems odd to have the earliest jobs processed last)
- Parallel processing of input and output files (starts sequential by default to reduce the CPU overhead, but is enabled if we ever see too long write/read)
- More insights scopes
Distributed:
- Not avoiding local machine for XGE on startup
Both:
- Input file compression (disabled by default, need to better figure out when it's beneficial in a general case. Mostly for people with really slow I/O and XGE over VPN).
- More stats, also more dense stat output. Removed an unimportant one, added stats about the batches.

- This helps with overall system responsiveness when many shader workers are spawned at the same time
