Merge bitcoin/bitcoin#23565: doc: rewrite dependencies.md

893e18059f1f92a254aa2026312a769c0e711db6 doc: rework dependencies.md (fanquake)

Pull request description:

  This PR rewrites dependencies.md. The current list is hard to parse, includes information that is either incorrect and/or misleading, and duplicates info in other documentation. The list of dependencies is much smaller, because it's now just the actual dependencies of Bitcoin Core, not random Qt things, or the dependencies of other tooling. We don't need _another_ section on configure flag usage, or, to have duplicated lists of dependencies in other build docs, as that somewhat defeats the point of having dependencies.md, and just means more effort keeping things in sync.

-Controlling dependencies
-------------------------
-Some dependencies are not needed in all configurations. The following are some factors that affect the dependency list.
-
-#### Options passed to `./configure`
-* MiniUPnPc is not needed with `--without-miniupnpc`.
-* libnatpmp is not needed with `--without-natpmp`.
-* Berkeley DB is not needed with `--disable-wallet` or `--without-bdb`.
-* SQLite is not needed with `--disable-wallet` or `--without-sqlite`.
-* Qt is not needed with `--without-gui`.
-* If the qrencode dependency is absent, QR support won't be added. To force an error when that happens, pass `--with-qrencode`.
-* If the systemtap dependency is absent, USDT support won't compiled in.
-* ZeroMQ is needed only with the `--with-zmq` option.
-
-#### Other
-* Not-Qt-bundled zlib is required to build the [DMG tool](../contrib/macdeploy/README.md#deterministic-macos-dmg-notes) from the libdmg-hfsplus project.
