Final version of updates for 6.5: grdimage, colorbar, grdmix

[PaulWessel]

This PR takes over the function of the previous PR (#8241) which now has been absorbed and modified into this cleaner PR. It also makes further adjustments to the placement and pale dimensions related to the enhanced -Li|I[gap] option in colorbar. I also have added a test for this whose plot looks like this:

You can see the older PR for various new test plots that documents the working of grdmix and grdimage. I get zero failures with this branch, running with or without OpenMP, Plesae make sure you change to theimg-layout branch, select static as active server (export GMT_DATA_SERVER=static) and run all tests. If you find any issues under Windows or Linux please let me know.

The colorbar docs now states this:

I believe this is the last item to be merged into master before we release 6.5.

Report last updated at commit 03498f3

[seisman]

Looks good, but need to update the copyright year to 2024 to make the "Code Validator" workflow pass.

[joa-quim]

Can we merge this? I need to trig a GMT build in the Julia system.

[PaulWessel]

Yep, doing it now.

[PaulWessel]

Master is now up to date with all those changes and copyright year is now 2024.
Going to bed but will work on building installers and tar balls tomorrow.

[joa-quim]

OK, I'll build the Win installer tonight.

[anbj]

OK, I'll build the Win installer tonight.

Please also remember to do a Windows portable.

[PaulWessel]

Just fixed a few warnings and updated master. No big deal if you have started building yet.

[joa-quim]

If you want one with 1 or 2 weeks old, I have it here.

[joa-quim]

I built these 4 guys. Which one should we publish as 6.5?

[PaulWessel]

You can choose what you think is useful for Win users and possibly Julia users.

BTW, I fixed a half-dozen or so of warnings that were annoying me. Probably no need to rebuild your installers.
