graphics/lcms2: Update to 2.19.1

This is a bugfix release.

Note that one can use cmake, but upstream has not yet declared that to
be the official build system, so decline to switch.  (As usual, the
autoconf build works fine.)

Log message:
graphics/lcms2: Explain upstream's (very unclear) cmake status

I asked upstream a bunch of questions just now.   For now, avoid
jumping to cmake because 1) upstream hasn't said it's baked and 2)
usually new cmake systems have regressions and this one hasn't been
tested.

Log message:
lcms2: update to 2.19.

All tests pass.

"vulnerabilities" that are not real.
Utility program names generated by Visual Studio 2026 are now same as all other \ 
platforms.
Creating an output profile by cmsTransform2DeviceLink does not propagate \

Add the possibility of duplicating a NULL context for cloning defaults.
Small cleanup of CGATS parser
