Fix #79566: Private SHM is not private on Windows

We map the POSIX semantics of `IPC_PRIVATE` by creating unnamed file
mapping objects on Windows. While that is not particularly useful for
ext/shmop, which is the only bundled extension which uses `shmget()`,
it may be useful for external extensions.

Fix #79561: dns_get_record() fails with DNS_ALL

Since Windows has its own definitions of the `PHP_DNS_*` macros, we
have to use these when registering the PHP constants.

Fix #79467: data:// wrappers are writable

Despite the docs claiming that data: wrappers would not be writable[1],
they are implemented as writing to a memory stream. That does not seem
to be particularly sensible, so we disallow writing altogether.

Fix bug #79447

Partially reverts 846b6479537a112d1ded725e6484e46462048b35: instead of
throwing, this skips uninitialized typed properties when serializing objects.

This makes serialize with __sleep() behave the same as serialize()
without __sleep().

As in the non-__sleep() case, unserialize(serialize($x)) identity
may not be preserved due to replacement of uninitialized/unset
properties with default values. Fixing this will require changes to
the serialization format.

Closes GH-5396.
