bcachefs: create debugfs dir for each btree

Browse Source 
This creates a subdirectory for each individual btree under the btrees/
debugfs directory.

Directory structure, before:

/sys/kernel/debug/bcachefs/$FS_ID/btrees/
├── alloc
├── alloc-bfloat-failed
├── alloc-formats
├── backpointers
├── backpointers-bfloat-failed
├── backpointers-formats
...

Directory structure, after:

/sys/kernel/debug/bcachefs/$FS_ID/btrees/
├── alloc
│   ├── bfloat-failed
│   ├── formats
│   └── keys
├── backpointers
│   ├── bfloat-failed
│   ├── formats
│   └── keys
...
