This header is for providing the argument types for recv() and send()
when built to not use a dedicated config-[platfor].h file.
Remove the slow brute-force checks from configure and cmake.
This change also removes the use of the types for select, as they were
not used in code.

1. Re-enable `HAVE_GETADDRINFO` detection on Windows
Commit d08ee3c83d (in 2013) added logic
that automatically assumed `getaddrinfo()` to be present for builds
with IPv6 enabled. As it turns out, certain toolchains (e.g. original
MinGW) by default target older Windows versions, and thus do not
support `getaddrinfo()` out of the box. The issue was masked for
a while by CMake builds forcing a newer Windows version, but that
logic got deleted in commit 8ba22ffb20.
Since then, some CI builds started failing due to IPv6 enabled,
`HAVE_GETADDRINFO` set, but `getaddrinfo()` in fact missing.
It also turns out that IPv6 works without `getaddrinfo()` since commit
67a08dca27 (from 2019, via #4662). So,
to resolve all this, we can now revert the initial commit, thus
restoring `getaddrinfo()` detection and support IPv6 regardless of its
outcome.

2. Omit `bcrypt` with original MinGW
Original (aka legacy/old) MinGW versions do not support `bcrypt`
(introduced with Vista). We already have logic to handle that in
`lib/rand.c` and autotools builds, where we do not call the
unsupported API and do not link `bcrypt`, respectively, when using
original MinGW.
This patch ports that logic to CMake, fixing the link error:
`c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: cannot find -lbcrypt`

The CMake `try_compile` command is especially slow for

When using clang-cl on windows -fvisibility=hidden is not an known
argument. Instead it behaves exactly like MSVC in this case. So let's
make sure we take that path.
In CMake clang-cl sets both CMAKE_C_COMPILER_ID=clang and MSVC get's
defined since clang-cl is basically a MSVC emulator. So guarding like we
do in this patch seems logical.

Add three new CMake Find modules (using the curl license, but I grant
others the right to apply the CMake BSD license instead).
This CMake config is simpler than the autotools one because it assumes
ngtcp2 and nghttp3 to be used together. Another difference is that this
CMake config checks whether QUIC is actually supported by the TLS
library (patched OpenSSL or boringssl) since this can be a common
configuration mistake that could result in build errors later.
Unlike autotools, CMake does not warn you that the features are
experimental. The user is supposed to already know that and read the
documentation. It requires a very special build environment anyway.
Tested with ngtcp2+OpenSSL+nghttp3 and quiche+boringssl, both built from
current git master. Use `LD_DEBUG=files src/curl |& grep need` to figure
out which features (libldap-2.4, libssh2) to disable due to conflicts
with boringssl.
Closes#5359
We use `check_c_source_compiles` to check possible send/recv signatures
by reproducing the forward declarations from system headers. On Windows
the `winsock2.h` header adds dll linkage settings to its forward
declaration. If ours does not match the compiler warns:
warning C4273: 'recv': inconsistent dll linkage
Add `WINSOCK_API_LINKAGE` to our test signatures when it is defined so
that our linkage is consistent with that from `winsock2.h`.

With CMAKE_TRY_COMPILE_TARGET_TYPE set to STATIC_LIBRARY, the try_compile()
(which is used by check_c_source_compiles()) will build static library
instead of executable. This avoids linking additional libraries in and thus
speeds up those checks a little.
This commit also avoids #3743 (GSSAPI build errors) on itself with cmake
3.6 or above. That issue was fixed separately for all versions.
