Merge `URI` with `URI_With_Query`

[radeusgd]

After some followup work and discussion, we conjecture that it may be cleaner to merge the utility of URI_With_Query directly into the URI, to have more uniform handling.

The APIs should be merged, we may want to add following additional methods:

• to_java_uri - a counterpart of the old URI_With_Query.to_uri that converts to pure Java URI, if there are no secrets - it may be useful for user's interaction with other Java libraries. It will still throw an error if there are secrests - only Enso APIs are allowed to work with those.
• query_arugments : Vector (Pair Text (Text | Enso_Secret)) - it may be worth to be able to query what arguments are currently in the URI, in the parsed form (counterpart to query : Text which returns the arguments in already encoded form).
  • I think we should remove raw_query as it can cause more harm than good - query_arugments will be more generic and serve the purpose of raw_ better.
  • These query_arugments must report all arguments, both ones parsed by URI.parse as well as added with add_query_argument - there should be no distinction between how an argument was added.
• the underlying URI instance shall likely hold an Apache URIBuilder instead of raw URI, as that allows to parse the query args and allows for easier manipulation of the URI.
• while we are at it, it may be worth to add a / operator to URI that allows to extend the path with additional fragments, analogously to File./.

Progress: Getting all pending PRs forward - fixing some tests, a few already got merged. Work on merging URI with URI_With_Query. It should be finished by 2023-12-20.

Next Day: Next day I will be working on the same task. Continue - creating a common way to create a URI from a 'schematic' that may contain secrets inside of query or user_info. Addressing PR comments.
