test,ci: fix [AM]San, disable ASLR (#4365)

The kernel that ships with the new Ubuntu 22.04 CI image seems to have a
PIE slide that is bigger than the sanitizer runtimes can handle.

It makes ASan fail with thousands of "AddressSanitizer:DEADLYSIGNAL"
warnings, and MSan error with complaints about memory accesses outside
known ranges. Disabling address space layout randomization fixes both.

This commit also fixes a small bug in the platform_output test where
the cgroups v1 logic did not handle the "unlimited quota" special case
properly. Ubuntu 20.04 still uses cgroups v1.

win: almost fix race detecting ESRCH in uv_kill (#4341)

It might happen that only using `WaitForSingleObject()` with timeout 0
could return WAIT_TIMEOUT as the process might not have been signaled
yet. To improve things, first use `GetExitCodeProcess()` and check
that `status` is not `STILL_ACTIVE`. Then, to cover for the case that the exit
code was actually `STILL_ACTIVE` use `WaitForSingleObject()`. This could
still be prone to the race condition but only for that case.

cygwin: implement uv_resident_set_memory (#4333)

According to the documentation for Cygwin, the penultimate field
of /proc/pid/stat corresponds to the RSS, so the method is basically
the same as in the Linux version. The only difference is that getpagesize()
will return wincap.allocation_granularity(), but in this mapping, RSS is
calculated using wincap.page_size(), which can be accessed by sysinfo.mem_unit.

linux: fix uv_available_parallelism using cgroup (#4278)

uv_available_parallelism does not handle container cpu limit
set by systems like Docker or Kubernetes. This patch fixes
this limitation by comparing the amount of available cpus

in the cgroup.

linux: create io_uring sqpoll ring lazily (#4315)

It's been reported that creating many event loops introduces measurable
overhead now that libuv creates an sqpoll-enabled ring.

I don't really see any change in CPU time with or without this change
but deferring ring creation until it's actually used seems like a good
idea, and comes with no downsides that I can think of, so let's do it.

win/spawn: optionally run executable paths with no file extension (#4292)

Add a process options flag to enable the optional behavior. Most users
are likely recommended to set this flag by default, but it was deemed
potentially breaking to set it by default in libuv.
