Currently, the TLS backend used by vquic/ngtcp2.c is selected at compile
time. Therefore OpenSSL support needs to be explicitly disabled.

Closes #5148

This updates the ngtcp2 OpenSSL backend to follow the API change in
commit 32e703164 of ngtcp2.
Notable changes are:
- ngtcp2_crypto_derive_and_install_{rx,tx}_key have been added to replace
ngtcp2_crypto_derive_and_install_key
- the 'side' argument of ngtcp2_crypto_derive_and_install_initial_key
has been removed

- Add new error code CURLE_QUIC_CONNECT_ERROR for QUIC connection
errors.
Prior to this change CURLE_FAILED_INIT was used, but that was not
correct.

- Remove our cb_update_key in favor of ngtcp2's new
ngtcp2_crypto_update_key_cb which does the same thing.
Several days ago the ngtcp2_update_key callback function prototype was
changed in ngtcp2/ngtcp2@42ce09c. Though it would be possible to
fix up our cb_update_key for that change they also added
ngtcp2_crypto_update_key_cb which does the same thing so we'll use that
instead.

- Disable warning C4127 "conditional expression is constant" globally
in curl_setup.h for when building with Microsoft's compiler.
This mainly affects building with the Visual Studio project files found
in the projects dir.
Prior to this change the cmake and winbuild build systems already
disabled 4127 globally for when building with Microsoft's compiler.
Also, 4127 was already disabled for all build systems in the limited
circumstance of the WHILE_FALSE macro which disabled the warning
specifically for while(0). This commit removes the WHILE_FALSE macro and
all other cruft in favor of disabling globally in curl_setup.
Background:
We have various macros that cause 0 or 1 to be evaluated, which would
cause warning C4127 in Visual Studio. For example this causes it:
#define Curl_resolver_asynch() 1
Full behavior is not clearly defined and inconsistent across versions.
However it is documented that since VS 2015 Update 3 Microsoft has
addressed this somewhat but not entirely, not warning on while(true) for
example.
Prior to this change some C4127 warnings occurred when I built with
Visual Studio using the generated projects in the projects dir.

ERR_error_string(NULL) should never be called. It places the error in a
global buffer, which is not thread-safe. Use ERR_error_string_n with a
local buffer instead.

On macOS/BSD, trying to call sendto on a connected UDP socket fails
with a EISCONN error. Because the singleipconnect has already called
connect on the socket when we're trying to use it for QUIC transfers
we need to use plain send instead.

The ngtcp2 QUIC backend was using the MSG_DONTWAIT flag for send/recv
in order to perform nonblocking operations. On Windows this flag does
not exist. Instead, the socket must be set to nonblocking mode via
ioctlsocket.
This change sets the nonblocking flag on UDP sockets used for QUIC on
all platforms so the use of MSG_DONTWAIT is not needed.

This allows the function to figure out if a unix domain socket has a
file name or not associated with it! When a socket is created with
socketpair(), as done in the fuzzer testing, the path struct member is
uninitialized and must not be accessed.

The quiche debug callback is global and can only be initialized once, so
make sure we don't do it multiple times (e.g. if multiple requests are
executed).
In addition this initializes the callback before the connection is
created, so we get logs for the handshake as well.
