win: fix build for mingw32 (#3340)

Commit e9c524aa from pull request https://github.com/libuv/libuv/pull/3149
introduced a hard dependency on `GetHostnameW`, which isn't declared
yet in mingw distributions (see
https://github.com/msys2/MINGW-packages/issues/9667).

This prevents the current version of libuv from building on many mingw
distributions, until such time the next version of mingw is released with
the correct definition for `GetHostnameW`, preventing a lot of projects
depending on libuv from building on mingw properly, as not all
distributions will update to head immediately anyway.

Instead of waiting, let's find the definition ourselves using
`GetProcAddress` and use the pointer instead.

win: prevent tty event explosion machine hang

The tty subsystem on Windows was listening for console events from all
processes to detect when our console window was being resized. This
could cause an explosion in the number of events queued by the system
when running many console applications in parallel that all wrote to
their console quickly. The end result was a complete machine hang.

Now we determine, whenever possible, what our corresponding conhost.exe
process is and listen for console events from that process only. This
detection does not work in 32-bit applications running on 64-bit
Windows so those default to the old behavior of listening to all
processes.

win,pipe: refactor pipe read cancellation logic

* Don't silently ignore ERROR_OPERATION_ABORTED.

Code to silently ignore this error was added in c42a4ca, under the
false premise that this error is somehow equivalent to EINTR on posix
platforms. This isn't true; ERROR_OPERATION_ABORTED doesn't happen
unless the application explicitly aborts an I/O operation.

Silently ignoring this error elsewhere could potentially hide bugs,
hence libuv shouldn't do it. Instead, explicitly deal with it where
it is expected.

* Don't mark aborted reads as successful.

The worker thread used to call ReadFile() on synchronous pipes would
incorrectly mark cancelled read requests as successful, leading to
issues later on.

* Rely on main thread to restart aborted reads.

After a blocking ReadFile() call was cancelled, the worker thread
would previously attempt to restart it immediately, making
synchronization logic needlessly complex. Instead, we simply cancel
the operation, and leave it to the main loop to restart it if so
desired.

Since we now realy on the main thread to restart interrupted
ReadFile() calls, we can now have a single function interrupts a
synchronous read until the event loop restarts it again.

* Clean up uv__pipe_read_stop().

A single function to interrupt blocking reads also allows us to
remove weird logic in uv__pipe_read_stop() that quickly pauses and
unpauses a read operation in the hope of cancelling it.

* Assume CancelIo() and CancelSynchronousIo() are always available.

Since libuv doesn't support windows XP and Server 2003 any more, we
can assume that these APIs are always available, and do away with
branching around them.

compiler support. libuv doesn't support any compilers that lack
anonymous unions, but does support compilers such as VS 2008 that
complain about the presence of the DUMMYUNIONNAME identifier on an
anonymous union because their winapi headers do not define the
macro publicly.
