newbus: remove support for SINGLETON

Revert rest of de8dd262c43b since it's now unused.

jhibbits@ introduced this to give powerpc MMU functions IFUNC like
performance while retaining the kobj interface, speeding up operations
10-20%. Since there was only ever one instance of the mmu interface
active at any given time, we could cache the looked up results more
agressively.

powerpc migrated to using IFUNCs to get an even larger performance boost
in 45b69dd63e, deleting the two files it was added to in de8dd262c43b.

However, there's few, if any, other potential applications of this to
the tree today. It's now unused and undocumented. Retire it to eliminate
this wart and to preclude the need to document it. Should a simmilar
case arise in the future, the code is in git...

Add a 'SINGLETON' directive to kobj interface definition

Summary:
This makes the interface described in the definition file act like a
pseudo-IFUNC service, by caching the found method locally.

Applying this to the PowerPC MMU definitions, it yields a significant
(15-20%) performance improvement, seen in both a 'make buildworld' and a
parallel build of LLVM, on a POWER9 system.

sys: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Make kobj_methods constant.

These structures hold no information that is modified during runtime. By
marking this constant, we see approximately 600 symbols become
