Basic support for Unix domain sockets on Windows within
the limitations of the operating system itself: no
support for abstract addresses, datagram or
packet sockets and ancillary data.
This also fixes File::GetType on Windows to correctly
identify reparse points representing AF_UNIX sockets
as such, rather then identify them as links.
Finally, it is worth noting that there is an existing
discrepancy between POSIX OSes and Windows: on POSIX OSes
File(sockPath).existsSync() returns true, but on Windows the
same code returns false because Unix domain sockets are not
considered regular files by stat.
This CL does a bunch of refactoring around RawAddr class which
surves as a wrapper around various structures in sockaddr_* family.
Distinguishing anonymous AF_UNIX address from abstract AF_UNIX
address requires passing around the length of the address
structure. Thus we incorporate this information into
RawAddr. This will also make possible to properly support
full-range of abstract AF_UNIX addresses in the future because
supporting these requires properly handling embedded NUL bytes.

Android is based on Linux, so most of the files were identical
sans some subtle discrepancies caused by drift over time.
This discrepancies were making code base harder to maintain and in fact
were hiding bugs. For example, on Android eventhandler's implementation
of timers which relied on passing timeout to `epoll_wait` contained
a bug which was not present on Linux which used `timerfd` instead.

This relands https://dart-review.googlesource.com/c/sdk/+/205633
but without renaming TARGET_OS_IPHONE to DART_TARGET_OS_IPHONE.
It also changes uses of TARGET_OS_IOS to
DART_TARGET_OS_MACOS_IOS to be consistent with the rest of the
VM.
TargetConditionals.h for XCode 13 defines several
TARGET_OS_* preprocessor symbols that confuse the
Dart build. There is probably a more targeted fix
for this, but renaming the symbols that Dart uses
will also prevent this problem if more symbols
are added to the platform headers in the future.
See: https://github.com/dart-lang/sdk/issues/46499
TEST=It builds.

Support Unix domain sockets communication on Linux, MacOS and Android.
Changes:
1. Add a field for InternetAddressType named unix.
2. Constructor of InternetAddress gains one more optional field: type. InternetAddress(String address, {InternetAddressType type});
3. Add another constructor to InternetAddress which taks raw address/path for ip/unix addresses as an argument. InternetAddress.fromRawAddress(Uint8List rawAddress, {InternetAddressType type});
The operation for unix domain sockets communication is basically the same as normal sockets except an InternetAddress with type unix should be passed.
