1: Two passes writing to same UAV was not getting the RWBarrier transition.
2: Incorrectly transitioned to readable when accessing for indirect draw call or SRV.

Don't compile distance field shader permutations if bUseDistanceFields is unset or false
Added UAV output to pixel shader
Clear Tiny UAV uses command buffer ClearBuffer command instead of allocating a temp buffer and copying it to UAV

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
