Merge #20153: wallet: do not import a descriptor with hardened derivations into a watch-only wallet

Browse Source 
538be4219a wallet: fix importdescriptor silent fail (Ivan Metlushko)

Pull request description:

  Currently `importdescriptor` command will successfully import a descriptor with hardened derivations into a watch-only wallet while silently failing to expand the descriptor to fill the cache. This leads to a broken wallet state and failure to load such wallet due to missing cache on subsequent restart.
