* Impose new restrictions on paras init and cleanup
For upcoming PVF pre-checking feature we will need to impose a couple of
new restrictions for:
- `schedule_para_initialize`.
- `schedule_para_cleanup`.
Specifically, for the former we do not want to allow registration of
wasm blob that is empty, i.e. 0 bytes. While that currently already
does not make a lot of sense, it allows us to simplify the PVF
pre-checking logic: if this PR is deployed before the following changes
for PVF prechecking then we can be sure that no paras onboarding have to
have to go through the PVF pre-checking. In case, we deploy it
altogether this property will allow us to distingush paras that came in
before PVF pre-checking.
For `schedule_para_cleanup` we do not want to allow offboarding of paras
that are undergoing the upgrade process. While this is not a harsh
restriction this change allows us to avoid making the PVF prechecking
more complicated than it has to be.
* Add a test for schedule_para_initialize
* Link to `ParaLifecycle::is_stable` in docs.
* `schedule_para_{init,cleanup}` docs
Now they link to their original declarations in the pallet for more
details.
