Cooker: In MPCook Collect garbage based on the Operating System's MemoryPressure event, so that Standby memory does not cause spurious garbage collection.
In all cook modes, tweak the output during garbage collection to have less duplicate information.
In all cook modes, add a cooldown for GC when garbage collection is not impactful.

- Log out more DXGI Adapter information when enumerating adapters in D3D12RHI.
- Log out more SM6 relevant information when enumerating adapters in D3D12RHI.
- Log out driver versions when enumerating adapters in D3D12RHI. Had to silence all the log output from FPlatformMisc::GetGPUDriverInfo to make this usable.
- Adding more logging when D3D12 reports it's not supported.
- Adding more logging to WindowsDynamicRHI so it's easier to track what a system did and didn't support.
- Adding -ForceDisableSM6 command line flag to force D3D12RHI to think it doesn't support ERHIFeatureLevel::SM6.
- Adding -ForceZeroAdapters command line flag to simulate when D3D12RHI can't find any valid adapters.

IncludeTool warning: we can not create a duplicate definition of PLATFORM_USES_FIXED_GMalloc_CLASS because some platforms are setting it in headers rather than c++.
Change the c-language includes of LowLevelMemTrackerDefines to be predicated only on LLM_ENABLED_IN_CONFIG to avoid the need for the definition of PLATFORM_USES_FIXED_GMalloc_CLASS.
Fix implicit conversion warnings in VirtualAllocPageStatus.cpp.

The new driver detection method (using the setup API) did not set the UserDriverVersion in the same way as the other methods, so the function which extracted the number used for comparison didn't work correctly.
Also removed a bogus cvar from BaseEngine.ini while we're at it (r.DetectAndWarnOfBadDrivers has been removed from the code years ago).

*Make FPlatformMemory::GetStats cache memory stats per frame to prevent multiple costly platform calls per frame ( by default, has option to request non-cached values ).
*Update some calls to FPlatformMemory::GetStats to specifically request non-cached values.

Change ShaderCompiler OnMachineResourcesChanged to allow specifying the number of logical cores and physicalcores rather than reading it from the (immutable-per-process) FPlatformMisc::NumberOfCores.
Change the CookDirector to use physicalcorelimit and OnMachineResourcesChanged.
