bcachefs: RESERVE_stripe
Rework stripe creation path - new algorithm for deciding when to create
new stripes or reuse existing stripes.
We add a new allocation watermark, RESERVE_stripe, above RESERVE_none.
Then we always try to create a new stripe by doing RESERVE_stripe
allocations; if this fails, we reuse an existing stripe and allocate
buckets for it with the reserve watermark for the given write
(RESERVE_none or RESERVE_movinggc).
