Do not use node's local storage if it is clear that an object will be
removed anyway as a redundant. It requires moving the changing local storage
logic from the validation step to the local target implementation.
It allows performing any relations checks (e.g. object locking) only if a
node is considered as a valid container member and is expected to store
(stored previously) all the helper objects (e.g. `LOCK`, `TOMBSTONE`, etc).

Core changes:
* avoid package-colliding variable naming
* avoid using pointers to IDs where unnecessary
* avoid using `idSDK` import alias pattern
* use `EncodeToString` for protocol string calculation and `String` for
printing

Make `FormatValidator.ValidateContent` to verify payload of `LOCK`
objects. Pass locked objects to `Locker` interface. Require from
`Locker.Lock` to return `apistatus.IrregularObjectLock` error on a
corresponding condition.
Also add error return to `DeleteHandler.DeleteObjects` method. Require
from method to return `apistatus.ObjectLocked` error on a corresponding
condition. Adopt implementations.

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

Values of object attributes must not be empty according to NeoFS
specification.
Make `FormatValidator.Validate` method to return an error if at least one
attribute has empty value.

Keys of object attributes must be unique according to NeoFS specification.
Make `FormatValidator.Validate` method to return an error if at least one
attribute is duplicated.

Wrap functions at `pkg/errors` return nil if error argument
was nil. fmt.Errorf always returns error so we need to add
missing error checks to the code.

According to nspcc-dev/neofs-api#136 tombstone body should store the same
attribute as in object header. If they are different, then check is failed
with `errTombstoneExpiration`.

The lifetime of an object can be limited by specifying a correspondin
well-known attribute. Node should refuse to save expired objects.
Checking objects in FormatValidator is extended with an expiration attribute
parsing step.

Linking object carries only identifier of the parent object. Fix Validate
method of FormatValidator to not validate parent object of the linking
object.
