gai_strerror() is not thread-safe on Windows (GH-15568)

First we refactor to have only a single usage of `PHP_GAI_STRERROR()`
left; then we drop the macro in favor of calling the different
functions conditionally in an ad-hoc style.

This is necessary because the return value of `php_win32_error_to_msg`
needs to be freed by the caller.

The error messages are no more inline with other error messages, since
`gai_strerror()` apparently always appends a period and a space.

We also properly configure IPv4/v6 on Windows. Since WSPiApi.h has been
created in 2000, so we can safely assume that it is available everywhere
nowadays. Furthermore, `gai_strerror()` is available regardless of
whether there is IPv6 support.

Support AVX-512 builds on Windows

"Since limited support for `/arch:AVX512` was added in Visual Studio
2017, and expanded in Visual Studio 2019"[1], we can safely offer this
option, since PHP 8.4 is supposed to build with Visual Studio 2022, and
it is unlikely that someone tries to build PHP 8.4 with Visual Studio,
requesting AVX-512 support.

Make vm_interrupt and timed_out atomic (#8327)

This is done by adding a new zend_atomic_bool type. The type
definition is only available for compiler alignment and size info; it
should be treated as opaque and only the zend_atomic_bool_* family of
functions should be used.

Note that directly using atomic_bool is complicated. All C++ compilers
stdlibs that I checked typedef atomic_bool to std::atomic<bool>, which
can't be used in an extern "C" section, and there's at least one usage
of this in core, and probably more outside of it.

So, instead use platform specific functions, preferring compiler
intrinsics.

Quote when adding to connection string in (PDO_)ODBC

Because the UID= and PWD= values are appended to the SQLDriverConnect
case when credentials are passed, we have to append them to the string
in case users are relying on this behaviour. However, they must be
quoted, or the arguments will be invalid (or possibly more injected).
This means users had to quote arguments or append credentials to the raw
connection string themselves.

It seems that ODBC quoting rules are consistent enough (and that
Microsoft trusts them enough to encode into the .NET BCL) that we can
actually check if the string is already quoted (in case a user is
already quoting because of this not being fixed), and if not, apply the
appropriate ODBC quoting rules.

This is because the code exists in main/, and are shared between
both ODBC extensions, so it doesn't make sense for it to only exist
in one or the other. There may be a better spot for it.

Closes GH-8307.

Add system ID entropy API

The `zend_system_id` is a (true global) system ID that fingerprints a process state. When extensions add engine hooks during MINIT/startup, entropy is added the system ID for each hook. This allows extensions to identify that changes have been made to the engine since the last PHP process restart.
