win,process: write minidumps when sending SIGQUIT (#3840)

This commit adds the ability to dump core when sending the `SIGQUIT`
signal on Windows. The change reads in the current registry setting for
local dumps, and attempts to write out to that location before killing
the process. See [collecting-user-mode-dumps] for registry and pathing
details. This behavior mimics that of the dumps created by the typical
Windows Error Reporting mechanism.

build: export compile_commands.json (#3968)

Add a missing assert that checks whether `uv_pipe_init()`
succeeded or not.

unix: use memcpy() instead of type punning (#3990)

Libuv makes no claim to being strict aliasing-clean but type punning
makes me feel unclean so replace it with memcpy().

build: remove freebsd and openbsd buildbots (#3974)

The buildbots are super flaky compared to other platforms and no one
seems invested enough to investigate. They don't add nearly enough value
for the friction they cause so away they go.

src: fix events/events_waiting metrics counter (#3957)

The worker pool calls all callbacks locally within the queue. So the
value of nevents doesn't properly reflect that case. Increase the number
of events directly from the worker pool's callback to correct this.

In order to properly determine if the events_waiting counter needs to be
incremented, store the timeout value at the time the event provider was
called.

The majority of uses for ASSERT_EQ are to check if the return value is

linux: fix academic valgrind warning (#3960)

Fix a valgrind warning that only manifested with clang (not gcc!) by
explicitly passing 0L instead of plain 0 as the |sigsz| argument to
io_uring_enter(). That is, pass a long instead of an int.

On x86_64, |sigsz| is passed on the stack (the other arguments are
passed in registers) but where gcc emits a `push $0` that zeroes the
entire stack slot, clang emits a `movl $0,(%rsp)` that leaves the upper
32 bits untouched.

It's academic though since we don't pass IORING_ENTER_EXT_ARG and the
kernel therefore completely ignores the argument.

linux: introduce io_uring support (#3952)

Add io_uring support for several asynchronous file operations:

- read, write
- fsync, fdatasync
- stat, fstat, lstat

io_uring is used when the kernel is new enough, otherwise libuv simply
falls back to the thread pool.

Performance looks great; an 8x increase in throughput has been observed.

src: switch to use C11 atomics where available (#3950)

Switch all code in unix/ to use C11 atomics directly.

Change uv_library_shutdown() to use an exchange instead of load/store.

Unfortunately MSVC only started supporting C11 atomics in VS2022 version
17.5 Preview 2 as experimental. So resort to using the Interlocked API.
