makesyscalls: don't make syscall.mk by default

We only want to produce syscall.mk for the main syscall table so default
to not producing it (send it to /dev/null) and add a syscalls.conf to
sys/kern to trigger the creation of sys/sys/syscall.mk. This eliminates
the need for entries in other syscalls.conf files and is a cleaner
pattern going forward.

syscalls.master: switch to CAPENABLED flags

Switch the main syscall table to use CAPENABLED flags rather than
capabilities.conf. This avoid synchronization issues between
syscalls.master and capabilities.conf (e.g. when renaming a syscall
during development).

For now, move capabilities.conf to sys/compat/freebsd32 and use it
there. Use of sys/compat/freebsd32/syscalls.master should be replaced
by makesyscalls.lua enhancements to allow the main one to be used.

This change results in no changes to generated files after running
`make sysent`.

sys/kern sysent: re-add dependency on capabilities.conf

r356868 inadvertently removed this, so changes to capabilities.conf were no
longer considered for being outdated.

sysent targets: further cleanup and deduplication

r355473 vastly improved the readability and cleanliness of these Makefiles.
Every single one of them follows the same pattern and duplicates the exact
same logic.

Now that we have GENERATED/SRCS, split SRCS up into the two parameters we'll
use for ${MAKESYSCALLS} rather than assuming a specific ordering of SRCS and
include a common sysent.mk to handle the rest. This makes it less tedious to
make sweeping changes.

Some default values are provided for GENERATED/SYSENT_*; almost all of these
just use a 'syscalls.master' and 'syscalls.conf' in cwd, and they all use
effectively the same filenames with an arbitrary prefix. Most ABIs will be
able to get away with just setting GENERATED_PREFIX and including
^/sys/conf/sysent.mk, while others only need light additions. kern/Makefile
is the notable exception, as it doesn't take a SYSENT_CONF and the generated
files are spread out between ^/sys/kern and ^/sys/sys, but it otherwise fits
the pattern enough to use the common version.

Set .ORDER for makesyscalls generated files

When either makesyscalls.lua or syscalls.master changes, all of the
${GENERATED} targets are now out-of-date. With make jobs > 1, this means we
will run the makesyscalls script in parallel for the same ABI, generating
the same set of output files.

Prior to r356603 , there is a large window for interlacing output for some
of the generated files that we were generating in-place rather than staging
in a temp dir. After that, we still should't need to run the script more
than once per-ABI as the first invocation should update all of them. Add
.ORDER to do so cleanly.

Add a new configuration file, kern/capabilities.conf (similar files
may be introduced for other ABIs in the future), which enumerates
system calls that are available in capability mode. When a new
system call is added to syscalls.master, it will also need to be
added here (if needed). Teach sysent parts to use this file to set
values for SYF_CAPENABLED for the native ABI.
