Tsvetomir Dimitrov 59f868d1e9 Deprecate para_id() from CoreState in polkadot primitives (#3979)
With Coretime enabled we can no longer assume there is a static 1:1
mapping between core index and para id. This mapping should be obtained
from the scheduler/claimqueue on block by block basis.

This PR modifies `para_id()` (from `CoreState`) to return the scheduled
`ParaId` for occupied cores and removes its usages in the code.

Closes https://github.com/paritytech/polkadot-sdk/issues/3948

title: Deprecate `para_id()` from `CoreState` in polkadot primitives
doc:
- audience: "Node Dev"
description: |
`CoreState`'s `para_id()` function is getting deprecated in favour of direct usage of the
`ClaimQueue`. This is the preferred approach because it provides a better view on what is
scheduled on each core.
