base: Remove support for the VTOC8 partitioning scheme

The removal of the sparc64 support in February 2020 obsoleted the
VTOC8 partitioning scheme as no other FreeBSD platform makes use
of it. Moreover, the code is bitrotting as nothing defines e. g.
LOADER_VTOC8_SUPPORT any more and, thus, should go now, too. With
this change, the following commits are reverted as far as VTOC8
is concerned and parts haven't already previously been deleted
along with prior sparc64 removals:
094fcb157d4c98211899cf09d06e2cf19149b7e0
a7d366e9589c95feda6f3bc78c59c6355d51f126
ba8d50d08b9df4e8213f9a6997ff6792ecebcd9b

The alignment example d9711c28efc4ec89ba5ea11f8fd63e9d0a7fc81b
added to the VTOC8 section of gpart.8 is folded into the MBR one.

This should finally conclude the deorbit of sparc64-specific bits.

We had joy, we had fun
we ran Unix on a Sun.
But that source and the song
of FreeBSD have all gone.

tslog: Optionally instrument pmap_zero_page

Booting an amd64 kernel on Firecracker with 1 CPU and 128 MB of RAM,
pmap_zero_page is responsible for 4.6 ms of the 25.0 ms of boot time.
This is not in fact time spent zeroing pages though; almost all of
that time is spent in a first-touch penalty, presumably due to the
host Linux kernel faulting in backing pages one by one.

There's probably a way to improve that by teaching Firecracker to
fault in all the VM's pages from the start rather than having them
faulted in one at a time, but that's outside of FreeBSD's control.

This commit adds a TSLOG_PAGEZERO option which enables TSLOG on the
amd64 pmap_zero_page function; it's a separate option (turned off
by default even if TSLOG is enabled) since zeroing pages happens
enough that it can easily fill the TSLOG buffer and prevent other
timing information from being recorded.

tcp: Build RACK and BBR stacks as a part of LINT

When RACK and BBR were added to the kernel, they were put
behind 'WITH_EXTRA_TCP_STACKS=1'. Unfortunately that was
never added to any NOTES file, so RACK & BBR were not compiled
with the various LINT-NOINET, LINT-NOINET6, and LINT-NOIP kernels.
This lead to the stacks sometimes being broken.

This change:

- Fixes RACK so that it compiles with the various LINT-NO* kernels
- Adds WITH_EXTRA_TCP_STACKS=1 to all NOTES kernels so that
RACK and BBR are compile tested regularly
