Adding color to cursors

[wpkelso]

This does some basic work towards addressing #1065 , starting with the watch animation in both its standalone and ptr form. I liked nakotami's idea with the pencil coloring from here, so that has been added in as a starting point; other "real" cursors will eventually follow suit (zoom-in/zoom-out).

--EDIT--

This PR now encompasses not just the work addressing #1065, but also small modifications to many other cursor files to bring them more in-line with the rest of the set in addition to clarity improvements.

I tried not to touch the main bodies of cursors where possible, as well as keep similar icons on similar color-lines. I think it might be a good idea to keep the all-black set of cursors as an option available to the user for accessibility purposes.

What do you think about putting all the symbols for dnd-cursors on a colored circle like dnd-copy is? Some of these symbols are a bit harder to see in these versions. For example this feels like a clear step back for legibility:

I'm a little worried with making the working cursors blue that folks will naturally think this should be following their system accent color. Maybe there's something interesting we can do with rainbow colors here? Or maybe revert this for now and revisit

It looks like you accidentally included some changes for USB receiver icons in this branch

[wpkelso]

Not sure what happened with the USB changes, nothing actually changed there to my knowledge. However, I've reverted that file to main.

I reverted the watch cursors as well, I'll revisit them in the issue thread for a more thorough design exploration.

Changing to symbol-on-circle definitely helps with clarity for the dnd-cursors, although the size constraints meant I had to do some reworking of the symbols themselves.

If the waiting cursors were their own branch, I would merge those today. I think that's an easy win. Those look great

For some of the other icons, I think there's more work to do here. Especially making sure we're consistent with the main icon set, using the colors and icons and styles already established there. I'll open a PR today with what I mean there

I'm not really fully convinced on the way the magnifier icons have been colored. I think generally updating separate families in separate branches might be better here so we can merge in what's working and consider/iterate on others separately

There's also still some issue with this PR touching the USB receiver icon, which it shouldn't

[wpkelso]

@danirabbit I think the original badges I was working with here were based on an earlier version of the HIG versus what you've done in #1250 , and I just failed to realize it.

I'll go ahead and split this up and close this PR. Hopefully that will resolve the issue with the USB receiver icon (I thought it had been unified with what was on main but perhaps that got pulled in before I had added the precommit on my end and thus wasn't cleaned up on main).
