misc: export WTF8 conversion utilities (#4021)

As promised in #2970, this attempts to migrate code to a common set of
utilities in a common place in the code and use them everywhere. This
also exports the functionality, since the Windows API with
WideCharToMultiByte is fairly verbose relative to what libuv and
libuv's clients typically need, so it is useful not to require clients
to reimplement this conversion logic unnecessarily (and because Windows
is not 64-bit ready here, but this implementation is.)

win,fs: don't modify global file translation mode

The MSVC runtime provides a global variable that can be used to set the
default file translation mode so that file open calls don't need to
explicitly specify that mode.

libuv was changing that global mode to binary from its default of text.
However, libuv doesn't actually need to do that anymore, and the
application may not want the default changed under it. This change stops
libuv from modifying that global mode.

win,pipe: fix IPC pipe deadlock

This fixes a bug where IPC pipe communication would deadlock when both
ends of the pipe are written to simultaneously, and the kernel pipe
buffer has already been filled up by earlier writes.

The root cause of the deadlock is that, while writes to an IPC pipe are
generally asynchronous, the IPC frame header is written synchronously.
So when both ends of the pipe are sending a frame header at the same
time, neither will read data off the pipe, causing both header writes
to block indefinitely.

Additionally, this patch somewhat reduces the spaghetti level in
win/pipe.c.

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.
