darwin: remove unused fsevents symbol lookups (#3867)

One hasn't been in use since 2017, the other since 2013.

test: unflake fs_event_watch_dir test (#3863)

Increase the timer interval. That hopefully ameliorates the problem of
FSEvents.framework missing events on the macOS CI buildbot.

Not really a fix, more a mitigation.

build: drop qemu-alpha from ci matrix (#3848)

As of recent, the fs_partial_read and fs_partial_write tests reliably
fail on that architecture.

An upgrade from Ubuntu 20.04 to 22.04 on the CI machines is suspected,
not any changes in libuv itself.

Perhaps it's possible to work around it in the tests but as Alpha is a
dead architecture, it doesn't seem worthwhile to sink time in that.
Let's remove it from the CI matrix instead.

win: fix fstat for pipes and character files (#3811)

Calling uv_fs_fstat for file types other then disk type was resulting in
error on Windows while it was retrieving data on Linux. This change
enables getting fstat for pipes and character files on Windows with data
fetched being as reasonable as possible.

A simple test is also added to check this behavior on all platforms. It
uses stdin, stdout and stderr. uv_fs_fstat needs to pass with disk files
pipes and character files (eg. console).

This commit also moves FreeBSD to tier 2 because it isn't actually

src: add new metrics APIs (#3749)

The following metrics are now always recorded and available via the new
uv_metrics_info() API.

* loop_count: Number of event loop iterations.
* events: Total number of events processed by the event handler.
* events_waiting: Total number of events waiting in the event queue when
the event provider request was made.

Benchmarking has shown no noticeable impact recording these metrics.

darwin: use hw.cpufrequency again for frequency info (#3679)

This reverts commit 87f076515937345fda1a1dbc598f34e65e1b81c7 and
implements a work-around instead. This has been reported to be
unnecessary, and also returns the wrong answer (off by exactly 100x),
so it is not particularly useful.

This also reverts the bugfixes to the original PR:

Revert "macos: fix memleaks in uv__get_cpu_speed"
This reverts commit d2482ae121e0ae5d0cf0934b2e93cee81a4ac5ed.

The expected behavior on failure to read this info is to report 0 (for
example
https://github.com/libuv/libuv/blob/8975c05d199558b0cc2e98f26ce33c6090d1
d7a1/src/unix/linux.c#L834), which is which was not the case before
this PR for macos.

However hw.cpufrequency sysctl seems to be missing on darwin/arm64
(Apple Silicon), so we instead hardcode a plausible value. This value
matches what the mach kernel will report when running Rosetta apps.
