- Fleshed out the comment for the function to better describe the return value.

- This allows us to provide the user with more ways to customize the virtualization and return more detailed info about it if the calling code wishes to log additional info. In both cases we can extend the options and the data returned without changing the API.
- Previously if we virtualized a package that was not checked out in revision control we would warn the user and then skip updating the package file on disk. This means the payloads would be uploaded but the user would be left with no local changes. Since sometimes we know we don't need to check out any package (virtualizing the packages in a change list for example) we don't want to always incur the cost of polling reivision control to see which packages do need checking out. This is why we now allow the caller to request package files be checked out via the new options enum EVirtualizationOptions.
-- If the EVirtualizationOptions::Checkout flag is provided we will poll the revision control status of all package files and then check out those which need it.
-- We still check if packages can be modified and warn the user if they can't, as package files could be locked in other ways.
- Added a new utility function to SourceControlUtilties to make it easier to check out packages. There is similar functionality elsewhere in the code base but the virtualization module is too low level to make use of it.
- Updated existing code that calls ::TryVirtualizePackages and add cases of ''using namespace UE::Virtualization' where required to improve readability.
- The UnrealVirtualizationTool now supports a new cmdline option "-checkout" that can be used when virtualizing packages. This will checkout any package that was actually virtualized so the result can be saved back out to the workspace domain. This means we no longer require the caller to have checked out the packages before running the tool.

- The mirage specific code is disabled behind the define UE_USE_VIRTUALBULKDATA, this means that some code paths in Texture/Mesh are much more complex than they need to be as we support both old and new paths. Once the system has been turned on and confirmed to cause no issues then this will be stripped out.
- SavePackageUtilities.cpp, SavePackage.cpp and SavePackage2.cpp are editgrates rather than integrations as those files have changes in DevCooker that we don't want to bring over immediately.
- Also includes a prototype system for storing bulkdata in a sidecar file in the workspace domain rather than in the .uasset/.umap file which although has been discontinued as part of mirage, will have applications for future work for non-virtualized projects and/or text based assets.
