CI: add Makefile target to verify default highlighting groups are present
When adding new highlight groups, one needs to make sure to also add a
"default link NewHlGroup ExistingHlGroup" in highlight.c code, so that
when resetting a color scheme the old color won't be left behind.
So add a Makefile in the 'ci' directory that verifies that all
documented '*hl-<groupname>' from the documentation are either reflected
in the source code, or belong to a list of 'known to be ignored'
highlight groups and let that check run as part of the CI test suite.
