- FAssetImportInfo is now marked as USTRUCT and is stored as a member value on UAssetImportData rather than using inheritance. This makes customization writing much easier and better affords UObject interoperability.
- Removed UAssetImportData::bDirty as it was only every used to enable/disable a button on the static mesh editor, and its presence caused confusion and inconsistency.
- Fixed issue where timestamps did not get updated correctly
- Fixed various reimport paths that were not updating their source file information correctly.
This addresses UETOOL-466 and UE-16406.

Use r.PS4StandardWriteLocks=1 to enable the old default functionality for testing if necessary.
