xfs: introduce fake roots for ag-rooted btrees
Create an in-core fake root for AG-rooted btree types so that callers can generate a whole new btree using the upcoming btree bulk load function without making the new tree accessible from the rest of the filesystem. It is up to the individual btree type to provide a function to create a staged cursor (presumably with the appropriate callouts to update the fakeroot) and then commit the staged root back into the filesystem.
