FStaticMeshLODResources are now ref counted to prevent deleting the data while it is being accessed.
The stream out strategy now involves waiting several frame before streaming out, if there are external references to the LOD.
This number of checks is controlled by the new "r.Streaming.MaxReferenceChecksBeforeStreamOut" with a default value of 3.
Disabled StaticMesh streaming while in the editor to prevent issues with tools.
UNiagaraDataInterfaceStaticMesh now correctly support preview feature level and in game LOD streaming.
LODData that is cached initialization time is now invalidated if that LOD is streamed out, this
only affect GPU sampling and FStaticMeshFilteredAreaWeightedSectionSampler).

Collect detailed information on roundtripping error to pinpoint problems much faster.
Implement Identical() for some movie scene evaluation types to fix UnversionedPropertySerializationTest
Previous Identical() implementation returned false since they were only compared to default value and was known to always differ from default. UPS test requires proper Identical() implementation.

There was a mismerge of the fix 11091798 when it was moved from dev-core to a private branch which reintroduced the exception for FBulkDataBase::CanLoadFromDisk, so that it would pass inlined data if it was running from IoStore. This would then quite rightly trigger issues in our automated tests.
Restored the original fix in 11091798.

- Attempting to memory map inline data will give a log error(as the original implementation did but will not attempt to actually memory map it as it is very unlikely that inline data would have the correct alignment requirements for the operation to succeed so to keep the code simple we just serialize the inline data which was the existing fallback behaviour anyway.
- Added the memory mapping implementation as it's own method (MemoryMapBulkData) since we only need to support the non-inline case.
- Added a flag (bShouldForceLoad) that when true will force the BulkData2 data to be streamed in immediately. Currently used as a fallback if the memory mapping fails (all callers assume 100% success) but I made it generic enough that we could use it for something else if the use case occurs.
- This is a fairly quick fix to unblock testing, future work includes:
- Reduce the added memory bloat (adding 2 additional pointers to BulkData2)
- Implement copy/assignment of memory mapped BulkData (based on the above work)
