* [Issue #28394] Implemented a migration process for Google Drive cloud drives to hierarchical chunk organization:
- Large drives with > 490,000 chunks will be automatically migrated.
- Can be disabled by setting GoogleDrive_UpgradeChunkOrganizationForLargeDrives to false.
- Any drive can be migrated by setting GoogleDrive_ForceUpgradeChunkOrganization to true.
- The number of concurrent requests to use when migrating can be set with GoogleDrive_ConcurrentRequestCount (defaults to 10).
- Migration can be interrupted (e.g. system shutdown) and will resume from where it left off on the next mount.
- Once a drive is migrated (or in progress), an older version of StableBit CloudDrive cannot be used to access it.
* [Issue #28394] All new Google Drive cloud drives will use hierarchical chunk organization with a limit of no more than 100,000 children per folder.
