Use MACHINE_CPUARCH when checking for arm64

Use MACHINE_CPUARCH with arm64 (aarch64) when we build code that could run
on any 64-bit Arm instruction set. This will simplify checks in downstream
consumers targeting prototype instruction sets.

The only place we check for MACHINE_ARCH == aarch64 is when building the
device tree blobs. As these are targeting current generation ISAs.

Another round of attempting to squelch -Wdeprecated-declarations, which
has become very trigger-happy with libc++ 9.0.0.

It does not help that gcc's implementation of this warning is even more
trigger-happy, in the sense that it already warns on the declaration
itself, not when you are using it. This is very annoying with our use
of -Wsystem-headers. That should really be disabled for gcc.

pkgbase: Create a FreeBSD-utilities package and make it the default one

The default package use to be FreeBSD-runtime but it should only contain
binaries and libs enough to boot to single user and repair the system, it
is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

Fix warnings with lib/libpmc

* Use `MIN` instead of similar hand rolled macro.
* Sort headers.
* Use `errno.h` instead of `sys/errno.h`.
* Wrap the argument to sizeof in parentheses for clarity.
* Remove `__BSD_VISIBLE` and `_XOPEN_SOURCE` #defines to mute warnings about
incompatible snprintf definitions.

This fixes a number of warnings I've been seeing lately in my builds.

Sort makefile variables per style.Makefile(9) (`CFLAGS`/`CWARNFLAG.gcc`) and
bump `WARNS` to 3.
