darwin: simplify uv_hrtime

mach_continuous_time is available since macOS 10.12, but our minimum
version is 11, so no need for a workaround.

Also, prefer that to `clock_gettime_nsec_np(CLOCK_MONOTONIC_RAW)` which
the documentation suggests
(https://developer.apple.com/documentation/driverkit/3438077-mach_continuous_time)
since the latter calls mach_timebase_info every time, unnecessarify: https://github.com/apple-open-source/macos/blob/49dcc07a40d19fa97384033a8398dae5d00d11a1/Libc/gen/clock_gettime.c#L107

This reverts commit 87f076515937345fda1a1dbc598f34e65e1b81c7 and

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:

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.

macos: fix the cfdata length in uv__get_cpu_speed (#3356)

We observed crashes inside CFRelease in uv__get_cpu_speed on the new
Mac Book Pro (arm) hardware. The problem is that the stack got
clobbered. On the new mac hardware the returned length is 8.

For the 4 byte case, a temp variable is used to avoid having to add
endian-sensitive offsets.

Revert "memory: add uv_replace_allocator"

memory: add uv_replace_allocator

With uv_replace_allocator, it's possible to override the default
memory allocator's malloc and free calls with functions of the user's
choosing. This allows libuv to interoperate with projects requiring a
custom memory allocator.

Internally, all calls to malloc and free have been replaced with
uv__malloc and uv__free, respectively. The uv__malloc and uv__free
functions call malloc and free unless they have been overridden by a
previous call to uv_replace_allocator.

As part of this change, the special aligned memory allocations
performed in src/win/fs-event.c have been replaced with standard
allocations. The 4-byte alignment being requested in this file was
unnecessary, since standard allocators already guarantee at least an
8-byte alignment.
