Live++ reads object files at startup for game modules, and assigns unique ids to each compiland (used to disambiguate static variables). When compiling the patch, these compilands are modified to reference a unique id for the unity blob, causing the variables to be reconstructed.
Solution is to generate a JSON file to each output directory containing object files containing the mapping, and to use that to assign compiland ids at startup.

These variables (and their dynamic initializers) were being treated as new, rather than being linked back to their original instances. UBT now outputs a mapping of object files to their original unity object file during a live coding compile, which allows Live++ to disambiguate between new and reconstructed instances.

Now stores the linker environment block in the live coding manifest, and adds it to the cache before executing the linker.

- This feature allows different chunk layout on different platforms.
- Most mapping work is done in AssetRegistryGenerator.
- Terminology of ChunkID and Pakchunk Index are now separated and they are no longer the same if chunk id to pakchunk index mapping is defined. The ChunkIDs in FAssetData is not renamed to keep consistency, but it actually is pakchunk index. FAssetData.ChunkIDs is used for ChunkInstall.
- Chunks with encryption key guid or unique assetregistry name are not allowed to be mapped. There are code to filter out those chunks and log errors while initializing mapping
- CheckChunkAssetsAreNotInChild() and ResolveChunkDependencyGraph() is skipped when making build for XboxOne and PS4, since they are not needed. If for some reason, we need chunk dependency on console builds, we need to implement per-platform dependency graph, since now we support different chunk layout on different platforms.
- Disabled a few pak file overide rules for console builds, since they should only be applied to builds with Kairos chunk layout.
#test A preflight was kicked and tested on PS4 and XboxOne. No new issue was found.
