Merge bitcoin/bitcoin#31961: Require sqlite when building the wallet

36b6f36ac4 build: require sqlite when building the wallet (Sjors Provoost)

Pull request description:

  Require that sqlite is available in order to compile the wallet. Removes instances of `USE_SQLITE` since it is no longer possible to not have sqlite available.

  The `NO_SQLITE` option is dropped from depends.

  This is another step towards dropping the legacy wallet, extracted from #31250.
