Make `DB.IterateCoveredByTombstones` to not pass locked objects to the
handler. The method is used by GC, therefore it will not consider locked
objects as candidates for deletion even if their tombstone is expired.

After introduction of LOCK objects (of type `TypeLock`) complicated
extended its behavior:
* create `lockers` container bucket (LCB) during PUT;
* remove object from LCB during DELETE;
* look up object in LCB during EXISTS;
* get object from LCB during GET;
* list objects from LCB during LIST with cursor;
* select objects from LCB during SELECT with '*'.

Implement `DB.Lock` method which marks list of the objects as locked by
another object. Only regular objects can be locked.

Create class of container buckets with `LOCKED` suffix. Put identifiers
of the objects of type `LOCK` to these buckets during `DB.Put`.

After `putsvc.Service` started to support additional container broadcast
of the saved objects there is no more need to perform broadcast of
tombstone object in `deletesvc.Service`.
Make `putsvc.Service` to perform additional broadcast of `TOMBSTONE`
objects. Remove `broadcastTombstone` stage from `deletesvc.execCtx`,
from now it is encapsulated in `saveTombstone` stage. Remove no longer
needed `putsvc.PutInitPrm.WithTraverseOption` method.

There are several cases when we need to spread the object around the
container after its primary placement (e.g. objects of type TOMBSTONE).
It'd be convenient to support this feature in `putsvc.Service`.
Add additional stage of container broadcast after the object is stored.
This stage is carried out no more than once and does not affect the
outcome of the main PUT operation.

Make all operations that related to `neofs-api-go` library be placed in `v2`
packages. They parse all v2-versioned structs info `neofs-sdk-go`
abstractions and pass them to the corresponding `acl`/`eacl` packages. `v2`
packages are the only packages that do import `neofs-api-go` library. `eacl`
and `acl` provide public functions that only accepts `sdk` structures.

Remove `Object` and `RawObject` types from `pkg/core/object` package.
Use `Object` type from NeoFS SDK Go library everywhere. Avoid using the
deprecated elements.

Similarly to `Get`. Also fix a bug where `ErrNotFound` is returned
instead of `ErrRangeOutOfBounds`.

Metabase is expected to contain actual information about objects stored
in shard. If the object is present in metabase but is missing from
blobstor, peform an additional attempt to fetch it directly without
consulting metabase. Such a situation is unexpected, so error counter
is increased for the shard which has the object in the metabase. We
don't increase error counter for the shard which has the object in
blobstor, because some garbage can be expected there. In this
implementation there is no overhead for objects which are really
missing, i.e. are not present in any metabase.
