Add rtw88 firmware to DVD package set

Add net/wifi-firmware-rtw88-kmod since it is no longer included in
the base system on 15.x. (It is present in 14.x, so this change will
not be MFCed.)

Modernize DVD package set in preparation for 14.1

Remove archivers/unzip (now in base) and emulators/linux_base-c7 (old
and unlikely to be useful without other linux packages being installed),
ports-mgmt/portmaster (now largely obsolete and discouraged in favour
of using pkg and binary packages) and x11-drivers/xf86-video-vmware
(questionably useful).

Replace devel/git with devel/git@lite (sufficient for most purposes),
and adjust the "ensure the ports exist to sanitize the list" code to
ignore the @lite part when checking that /usr/ports/devel/git exists.

Add sysutils/seatd and x11-wm/sway for wayland support.

release: Use the ABI of the target release to fetch packages

- Point --rootdir at the installed destdir in the dvd tree. This
causes pkg to determine the ABI from the installed destdir instead
of the host's binaries. Previously the result was that packages
for the host's ABI were always downloaded breaking cross-releases
(e.g. arm64 releases built on an amd64 host included amd64
packages on the DVD ISO image rather than arm64 packages). This
also handles version mismatches, and I tested this by cross-building
a 15.x arm64 release on a 14.x amd64 host.

- As a result, pkg now does a chdir(3) to the rootdir before running,
so the -o argument to fetch needs to be updated to be relative to
rootdir instead of the CWD as make runs.

- Add a new ROOTDIR variable to limit references to "dvd" to one
place. Ideally ROOTDIR would be an argument to this script so
that it didn't really know about the dvd layout at all.

- While here, simplify creation of symlinks by just using a longer
path to the link name instead of using 'cd' in the shell before
invoking ln(1). Also use ln -sf to create the pkg.pkg symlink
rather than rm + ln.

Update pkg-stage.sh to be compatible with pkg-1.4.x.

In 1.3.x and earlier, ABI format is, for example,
freebsd:11:x86:64.

In 1.4.x, ABI format is FreeBSD:11:amd64, and a new
configuration entry, ALTABI, is: freebsd:11:x86:64.

Export PKG_ABI and PKG_ALTABI accordingly, and if
PKG_ALTABI is set, create a symlink within the dvd
PKG_CACHEDIR so both new and old ABI directories
exist.

Add forward-compatibility glue with pkg-1.3:
- Use ASSUME_ALWAYS_YES=YES instead of ASSUME_ALWAYS_YES=1
since pkg-1.3 expects "yes" or "true" values.
- Before exporting PKG_ABI, strip extra characters from what
is parsed from 'pkg -vv'. This causes problems further down
when creating the packages directory for inclusion on the
dvd1.iso. Previously PKG_ABI would be 'freebsd:9:x86:64',
but now is '"freebsd:9:x86:64";' in pkg-1.3

Update the pkg-stage target to be more compatible with pkg-1.2:

- Remove architecture-specific pkg-stage.conf files, consolidate,

- Use 'pkg -vv' to determine the ABI, which is used as the
cache directory.

Prior to these changes, it would be possible for pkg-stage to fetch
conflicting binary packages from multiple repositories.

Add a script and configuration files to fetch pre-built packages
from pkg.FreeBSD.org for inclusion on release medium (dvd1.iso).

The script sources ${.CURDIR}/${TARGET}/pkg-stage.conf, which sets
several environment variables, such as the pkg(8) ABI, PACKAGESITE,
PKG_DBDIR, and PKG_CACHEDIR. PKG_CACHEDIR is set to the directory
on the release medium used by bsdconfig(8) (/packages/${ABI}). ABI
is determined by output of 'make -C /usr/src/release -V REVISION'.
See pkg.conf(5) for descripton on other variables set here.

The list of packages to include are set within the configuration
file.

The script and configuration files are intended to be run by the
'make dvd' target within the release directory, and assume the
release is built within a chroot environment (such as by using
release.sh).

Relevant updates to release/Makefile will follow.
