Merge #17138: Remove wallet access to some node arguments

Browse source 
b96ed03962 [wallet] Remove pruning check for -rescan option (John Newbery)
eea462de9c [wallet] Remove package limit config access from wallet (John Newbery)

Pull request description:

  Removes wallet access to `-limitancestorcount`, `-limitdescendantcount` and `-prune`:

  - `-limitancestorcount` and `-limitdescendantcount` are now accessed with a method `getPackageLimits` in the `Chain` interface.
  - `-prune` is not required. It was only used in wallet component initiation to prevent running `-rescan` when pruning was enabled. This check is not required.

  Partially addresses #17137.
