* Enable Gridstore payload index storage, rename storage types
* Respect payload_index_skip_mutable_rocksdb feature flag
* Minor cleanup
* Fix map payload index Gridstore semantics, only create files if desired
The semantics of backing storages in payload indices are inconsistent.
This aligns the Gridstore backing storage to our RocksDB backing
storage, matching the create/open/load behavior. Now, it will only
create Gridstore files on disk if we request it to do so.
This commit only implements it on the map index. In following comments
the same will be implemented in all other payload indices too.
* Apply same Gridstore semantics to other payload index types
* Rename create parameter to create_if_missing
* Fix bench compilation errors
* bq encodings

* Fix tests and benches
* Rename (some) *_measured functions back to original
* implement mmap sparse vector storage
* add to VectorStorageEnum
* clippy
* add tests, fix both simple and mmap storages
* smol correction on total_vector_count
* add sparse storage type to config
* fix reading config without storage type
* generate openapi
* use blob_store by path
* hidden setting to enable new storage
* validate existing path in `BlobStore::open()`
* use new dir for each sparse vector name
* fix and rename `max_point_offset`
Plus some extra refactors
* add storage compat test, to always check both storages work
* fix opening of storage + other misc fixes
* FIX!!!
`Unset` operations in the Tracker weren't updating the
`next_pointer_id`. So, when reopening the storage, those points wouldn't
get marked as deleted in the bitslice, thus creating the illusion that
they should exist, when they did not.
* refactor naming from `iter_*` to `for_each_*`
* fix checking for BlobStore existance
* fix typo
* fix error message
* better docs for open_or_create
* fix after rebase
