graphics/darktable: Update to 4.2.0

Release notes:
https://github.com/darktable-org/darktable/releases/tag/release-4.2.0

The work was done by Matthias Andree (mandree@) in
`graphics/darktable42`. Some of the style fixes were added in a separate
commit. Thank you Matthias!

The temporary port `graphics/darktable42` can be removed at the same
time, now that the main port is up-to-date.

graphics/darktable42: new port

photography workflow application and non-destructive raw developer
- a virtual lighttable and darkroom for photographers.

...with blanket approvals to dumbbell@, the maintainer of
graphics/darktable, currently at version 4.0.1.

Another year... this "darktable42" is intended to be a short-lived port
and package, and can be removed once we get around to updating
graphics/darktable proper to 4.2.

Thus, add a DEPRECATED port to let people know they will need to move
to graphics/darktable at some point, but omit the EXPIRATION_DATE.

I also tried to use LLVM14 or LLVM15 to build, but LLVM14's ld.lld
complains about duplicate symbols and LLVM15's about referencing symbols
from discarded sections. So let us use LLVM13 for now.  This may be
fixable by tweaking compiler options on darktable or librawspeed, but
let's have the port first and then tweak it.
