* Added extensions mv2 settings backup.
Added ExtensionsManifectV2Migrator which observes webstore extensions. When it detects certain extension is disabled by unsupported manifest version reason, it stores the Local Extension Settings and IndexedDB settings to ExtensionsMV2Backup directory in the browser profile.
Boolean feature param import_settings [requires backup_settings to be enabled]:
If enabled, ExtensionsManifectV2Migrator observes the brave-hosted extensions installation events. When brave-hosted extension in installed and there is the settings backup then ExtensionsManifectV2Migrator imports settings to the newly installed extension.
There was a flag from long ago that allowed you to select Crypto Wallets as your wallet. However if you did this, it no longer works. There is no one that can feasibly still be using this wallet because it hasn't worked for many versions
