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).

malloc(9): extend contigmalloc(9) by a "slab cookie"

Extend kern_malloc.c internals to also cover contigmalloc(9) by a
"slab cookie" and not just malloc/malloc_large. This allows us to
call free(9) even on contigmalloc(9) addresses and deprecate
contigfree(9). Update the contigmalloc(9) man page accordingly.

The way this is done (free(9) working for contigmalloc) will hide the
UMA/VM bits from a consumer which may otherwise need to know whether
the original allocation was by malloc or contigmalloc by looking at
the cookie (likely via an accessor function). This simplifies
the implementation of consumers of mixed environments a lot.

This is preliminary work to allow LinuxKPI to be adjusted to better
play by the rules Linux puts out for various allocations.
Most of this was described/explained to me by jhb.

One may observe that realloc(9) is currently unchanged (and contrary
to [contig]malloc/[contig]free an implementation may need access
the "slab cookie" information given it will likely be implementation
dependent which allocation type to use if size changes beyond the
usable size of the initial allocation).

Add malloc_domainset(9) and _domainset variants to other allocator KPIs.

Remove malloc_domain(9) and most other _domain KPIs added in r327900.
The new functions allow the caller to specify a general NUMA domain
selection policy, rather than specifically requesting an allocation from
a specific domain. The latter policy tends to interact poorly with
M_WAITOK, resulting in situations where a caller is blocked indefinitely
because the specified domain is depleted. Most existing consumers of
the _domain KPIs are converted to instead use a DOMAINSET_PREF() policy,
in which we fall back to other domains to satisfy the allocation
request.

This change also defines a set of DOMAINSET_FIXED() policies, which
only permit allocations from the specified domain.
