* Track the collation status in the collator protocol

This pr changes the collator protocol to track the status of a
collation. This is mainly used to log the status of a collation when it
is removed to inform the user if a collation maybe never reached a validator.

As futures most of the time are catching panics and we don't check this,
it could happen that we have some statement that isn't correct but the
test succeeds successfully.

* remove hack comment

* Update shared-memory to new version & refactor

This two are combined in a single commit because the new version of
shared-memory doesn't provide the used functionality anymore.

Therefore in order to update the version of this crate we implement the
functionality that we need by ourselves, providing a cleaner API along
the way.

* Significantly decrease the required memory for a workspace

For some reason it was allocating an entire GiB of memory. I suspect
this has something to do with the current memory size limit of a PVF
execution environment (the prior name suggests that). However, we don't
need so much memory anywhere near that amount.

In fact, we could reduce the allocated size even more, but that maybe
for the next time.

* Unlink shmem just after opening

That will make sure that we don't leak the shmem accidentally.

* Notify collators about seconded collation

This pr adds functionality to inform a collator that its collation was
seconded by a parachain validator. Before this signed statement was only
gossiped over the validation substream. Now, we explicitly send the
seconded statement to the collator after it was validated successfully.

Besides that it changes the `CollatorFn` to return an optional result
sender that is informed when the build collation was seconded by a
parachain validator.

* Add test

* Make sure we only send `Seconded` statements

* Make sure we only receive valid statements

* Review feedback

* CancelProxy uses `reject_announcement` instead of `remove_announcement`

* add back remove_announcement

* Revert "add back remove_announcement"
