The description of `i686-pc-linux-gnu` and `x86_64-pc-linux-gnu` is
incomplete and inconsistent with the rest. Fix this. Also use "64 bit"
consistently instead of "64-bit".

ae56b3230b depends: For mingw cross compile use -gcc-posix to prevent library conflict (laanwj)
Pull request description:
CMake parses some paths from the spec of the C compiler, assuming it will be the linker, resulting in the link to end up with `-L/usr/lib/gcc/x86_64-w64-mingw32/12-win32` on debian bookworm if both `-win32` and `-posix` variants are installed, and `-win32` is the default alternative.
This results in the wrong C++ library being linked, missing std::threads::hardware_concurrency and other threading functions.
To fix this, use the `-posix` variant of gcc as well when available. This fixes a regression compared to autotools, where this scenario worked.

ACK ae56b3230b. I've tested on both Debian Bookworm and Ubuntu 24.04 with the `g++-mingw-w64-x86-64` package installed. The resulting CMake internal configuration appears more accurate. For instance, on Ubuntu 24.04, for the `bitcoin-tx` target, the diff in `build/src/CMakeFiles/bitcoin-tx.dir/linkLibs.rsp` looks as follows:

Pull request description:
Continues #30005. Closes #17012..
This PR adds PCP (Port Control Protocol) from [RFC6887](https://datatracker.ietf.org/doc/html/rfc6887). This adds, in addition to the existing IPv4 port mapping (which now uses PCP, with fallback to NAT-PMP), support for IPv6 pinholing-that is, opening a port on the firewall to make it reachable.
PCP, like NAT-PMP is a simple UDP-based protocol, and the implementation is self-contained, so this gets rid of lthe libnatpnp dependency without adding a new one. It should otherwise be a drop-in replacement. NAT-PMP fallback is implemented so this will not make router support worse.
For now it is disabled by default, though in the future (not in this PR) we could consider enable it by default to increase the number of connectable nodes without adding significant attack surface.
To test:
```bash
bitcoind -regtest -natpmp=1 -debug=net
```
(most of the changes in this PR are, ironically, removing the libnatpmp dependency and associated build system and build docs)
## TODO
- [x] Default gateway discovery on Linux / FreeBSD
- [x] Default gateway discovery on Windows
- [x] Default gateway discovery on MacOS
- [x] Either solve FreeBSD compile issue (probably upstream issue) or remove FreeBSD support
## Things to consider for follow-up PRs
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1658764974 avoid unreachable nets (not given to -onlynet=)
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1658949236 could announce an addr:port where we do not listen (no -bind)
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1684368824 could announce the wrong port because it uses GetListenPort()
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1679709347 if we requested one port but another was assigned, then which one to use in the renewal?
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1772017020 Use `GetAdapterAddresses` to discover local addresses for Windows

In the Guix environment, `${BASEPREFIX}/${HOST}/native/bin` is added to
the `PATH` environment variable, causing CMake to search for package
configurations in the `native` subdirectory first.
Explicitly specifying the top-priority search prefixes for the
`Libmultiprocess` and `LibmultiprocessNative` packages resolves the
issue.
Currently, builds of libevent in depends, using CMake, fail on some
systems, like Alpine, with the following:
```bash
/bitcoin/depends/work/build/aarch64-unknown-linux-musl/libevent/2.1.12-stable-1516ed47ea8/evmap.c: In function 'evmap_signal_add_':
/bitcoin/depends/work/build/aarch64-unknown-linux-musl/libevent/2.1.12-stable-1516ed47ea8/evmap.c:456:31: error: 'NSIG' undeclared (first use in this function)
456 | if (sig < 0 || sig >= NSIG)
```
From what I can tell the `_GNU_SOURCE` "detection" in libevents CMake build
system, never? really worked, and it's not clear what a nice fix is.
For now, always use `_GNU_SOURCE` when building libevent in depends.
Now that we use the native compiler, and have fixed Qt, and these vars
are unset it Guix, we can remove the unsetting from our compiler command
here.
Fixes#21552.
8c935e625e depends: Fix CMake-generated `libevent*.pc` files (Hennadii Stepanov)
Pull request description:
Broken out of #30454. This is a backport of the merged upstream PR: https://github.com/libevent/libevent/pull/1622.
Note that after #29835 we might end up dropping pkg-config and using the installed CMake files directly, but that depends on whether or not enough distros actually ship those files.
Either way, having fixed up .pc files won't hurt.

The CMake WIN32_WINNT autodetection is broken, and must be set
manually. We may want to set is explicitly in any case, but the
brokenness should also be fixed upstream.
Also patch out depends paths, that would cause non-determinism.
