Add clean support for Custom deployment paths

[ChristopherHaws]

The current implementation of STANDARD_CLEAN_PATHS does not have support for the CUSTOM_DEPLOYMENT_PATH environment variable which is used when MINECRAFT_PRODUCT="Custom". This change switches the logic to use the existing getGameDeploymentRootPaths helper method to better generate the clean paths.

This change makes clean work out of the box on linux, as shown here:

If this fallback is removed, getStandardCleanPaths could be passed to cleanTask instead since the full path is resolved without needing env var replacements. Going this route would mean that the cleanCollateralTask could probably be deprecated/removed.

[ChristopherHaws]

Something to note here is that getGameDeploymentRootPaths doesn't use the APPDATA path, it only uses LOCALAPPDATA which would be a breaking change I suppose? I don't think the copyTask task would work if LOCALAPPDATA wasn't set correctly so I don't think this would actually be breaking anything.
