Deprecate contigfree(9) in favour of free(9)

As of 9e6544dd6e02c46b805d11ab925c4f3b18ad7a4b contigfree(9) is no longer
needed and should not be used anymore. We leave a wrapper for 3rd party
code in at least 15.x but remove (almost) all other cases from the tree.

This leaves one use of contigfree(9) untouched; that was the original
trigger for 9e6544dd6e02 and is handled in D45813 (to be committed
seperately later).

vm: Retire vm_page_alloc_freelist{,_domain}()

Once upon a time, I created vm_page_alloc_freelist{,_domain}() to
support faster allocation of pages that were mapped by the partial
direct map on 32-bit MIPS. At the time, I expected that these
functions might find other uses too, but those other uses never
materialized. So, these functions have not been used for some time
now. Instead, people use the more general vm_page_alloc_contig().

cdefs(9): Start to document what sys/cdefs.h does

Start to document all the macros and such used to implment our
portability layer. It also describes what compilation environments
we support, what compilers we support and some of the details.

This is round one. All the macros, etc are in here, but some need
descriptions.

These macros, while FreeBSD internal only, do need documentation
on when/where to use them.

This man page likely needs better organization. While better
than sys/cdefs.h, the underlying chaos in that file was hard
to leave completely behind. Suggestions welcome.

This permits associating a resource type (e.g. SYS_RES_MEMORY) with a

I considered adding a new field to struct rman to store the type and
only providing rman_get_type as an accessor. However, changing
'struct rman' is an ABI breakage. I might revisit this in main, but
the current approach is MFC'able.

callout: retire callout_async_drain()

This function was used only in TCP before 446ccdd08e2a. It was born in
pain in 2016 to plug different complex panics in TCP timers. It wasn't
warmly accepted in phabricator by all of the reviewers and my recollection
of overall agreement was that "if you need this KPI, then you'd better fix
your code to not need it". However, the function served its duty well all
the way to FreeBSD 14. But now that TCP doesn't need it anymore, let's
retire it to reduce complexity of callout code and also to avoid its
further use.

device_set_descf() is a printf-like version of device_set_desc().

Allocation code has been transferred from device_set_desc_internal() to
device_set_desc_copy() and device_set_descf() to avoid complicating
device_set_desc_internal(). The "copy" argument in
device_set_desc_internal() has been replaced with a flag which is set
when the description string has been allocated with M_BUS.
