[BTRFS][UBTRFS][SHELLBTRFS] Upgrade to 1.8.0 (#4417)

Browse source 
v1.8 (2022-03-12):

- Added minimal support for fs-verity
- ~~Added test suite~~ Not in ReactOS
- Fixed incorrect disk usage statistics
- Fixed potential crashes when renaming stream to file or file to stream
- Fixed potential crashes when querying hard links on file
- Fixed potential hang when opening oplocked file
- Fixed minor issues also uncovered by test suite
