* process_collector: fill in most statistics on macOS
Unfortunately, the virtual memory, resident memory, and network stats will
require access to undocumented C functions. I was warned off of cgo in IRC
because it would then have to be enabled in a bunch of different projects that
use this module, but I already was against it because that would break the
ability to cross-compile. There is no interface to `dlopen` built into golang.
The `github.com/ebitengine/purego` module looks promising (I can cross-compile
and call these methods), but I'm currently getting unexpected results. I'll
follow up with that separately if I can get it working, but hopefully this stuff
is pretty uncontroversial.
Tested on macOS 10.14.6 (amd64), macOS 14.6.1 (amd64), and macOS 15.0 (arm64)
by spawning `/usr/bin/ulimit -a -S` and `/usr/sbin/lsof -c $my_process` from
the test exporter process, and `ps -o lstart,vsize,rss,utime,stime,command` from
the shell, and comparing results with the exported metrics.
I can't find documentation for `RLIMIT_AS` on macOS (specifically if it's in
bytes or pages). It's currently being reported back as `RLIM_INFINITY`, which
seems reasonable, because I've come across reports that the value is ignored
anyway[1]. The bash 3.2 code for the built-in `ulimit` divides the value
reported by `getrusage(2)` by 1024 when printing, as it does for `RLIMIT_DATA`,
which is documented as being bytes in `getrusage(2)`. The help for `ulimit`
indicates it prints both in kbytes, so it's reasonable to assume this is already
in bytes.

Now that 1.23 is out, update the supported version matrix to Go 1.21
through 1.23. This allows us to start using `log/slog`.
* Update generated tests.

this commit also adds an `includes` field to the dagger.json so the
initial SDK code generation runs faster as only the Dagger module source
is included

* Removeed go_memstat_lookups_total which was always set to 0; added runtime/metrics info to memstat metric helps.
I know we ideally should not remove any metric from default list, but
this one is always zero, so let's save everyone's money.
