Qu Wenruo 77db6bd402 btrfs-progs: rescue: introduce clear-uuid-tree 
[BUG]
There is a bug report that a corrupted key type (expected
UUID_KEY_SUBVOL, has EXTENT_ITEM) causing newer kernel to reject a
mount.

Although the root cause is not determined yet, with roll out of v5.11
kernel to various distros, such problem should be prevented by
tree-checker, no matter if it's hardware problem or not.

And older kernel with "-o uuid_rescan" mount option won't help, as
uuid_rescan will only delete items with
UUID_KEY_SUBVOL/UUID_KEY_RECEIVED_SUBVOL key types, not deleting such
corrupted key.

[FIX]
To fix such problem we have to rely on offline tool, thus there we
introduce a new rescue tool, clear-uuid-tree, to empty and then remove
uuid tree.

Kernel will re-generate the correct uuid tree at next mount.
