updating macports-libcxx to llvm-19+

[Gagan Sidhu]

first i want to thank the team for reworking the clang stuff.

clang-19 has now built successfully on lion. it wasn't bad at all. like a couple of lines.
	-i suspect someone on the team deliberately didn't make these changes to see if i cared. i do, i'm just busy with a bunch of things right now
		-hopefully if i get these e55 fuel pumps going in my 4matic tomorrow i'll have more time to enjoy my summer
			-like, sitting in the sun getting wasted in front of my 2020 i9 16" 5600m

what are the other prerequisites for tabling the update of macports-libcxx to clang-19?

we need to do this asap so i can try to push out fixes for node

hoping someone on the team is ready to receive and test a "patch" (as much of a joke as the patch is)

Thanks,
Gagan
