- Added shader pipeline hash as a key attribute.
- Added shaders from shader pipelines (they can have different code if RHI removes unused interpolators between the stages, like D3D does).

Plus - Fix rare shutdown check() failure when async file reads are still wainting in the FShaderPipelineCache.
Plus - Put back correct order of shutdown for FShaderCodeLibrary and FShaderPipelineCache as they can have outstanding aync file handles and we'll get a crash if they are closed after the module shutdown has deleted the FPakPrecacher singleton.

Shader code library was always emitting "<shadermodel>.scl.csv" files while cooking. This output data is only needed for users (or automated jobs) that update the PSO cache. With this change the configuration value "NeedsShaderStableKeys" needs to be set to true for platforms that use PSO (e.g. AndroidEngine.ini and IOSEngine.ini).
This saves diskspace and around 90 seconds on a iterative cook on a large project.

New AssetRegistryState::InitializeFromExistingAndPrune temporarily disabled until some bugs have been fixed.
Test Scenario:
1) BuildCookStageAndRun with these arguments: -platform=Win64 -configuration=Development
2) CookIterate with these arguments: -run=Cook -CookCultures=en -TargetPlatform=WindowsClient -unversioned -stdout -unattended -iterate
Wall Time Results (as an average of running step 2) two times):
Before: ~09:40 (580 seconds) cook commandlet time
After: ~02:30 (150 seconds) cook commandlet time
=> 07:10 (430 seconds ) faster, i.e. a ~ 3.9x speedup
Win32 FileSystem Results:
Before: 1.5 million GetFileAttribute calls and 1.2 million FindNextFile calls
After: 35 0000 GetFileAttribute calls and 1.6 million FindNextFile calls
=> ~400 000 calls to FindNextFile replaces ~1.5 million calls to GetFileAttribute
