wayland: cleanup popup implementation refactor.

[james-lawrence]

only piece I have left at this point is the screen implementation which i need to make some improvements to before I open a PR it.

after that I'll do a rebase against master for the wayland branch. I think at that point it'll be close enough to mainline. PRs after the screen stuff should be minor enhancements, bug fixes (I have 1 or 2 things I might fix), or code cleanup.

still a few small odds an ends to make it feature complete (but i havent needed them so... here we are. =)).

• bunch of the window builder API stuff needs to be wired up, titles, resizable, etc. these are small though and should be easily implemented as needed.
• tooltips, and modal window levels need to be implemented. but they should be identical to the dropdowns with a different positioning configuration.
• menus/dialog stuff. these can be shared with x11 i think?
• keymapping issues (copy/paste not generating the correct keystroke of x11/wayland).

should I create issues for these things?

I also think this is ready to merge into master! It is pretty close to the x11 backend.

yes should create an issue with missing shell/wayland labels

tooltips, and modal window levels need to be implemented. but they should be identical to the dropdowns with a different positioning configuration.

the positioning is exactly same 🤔

menus/dialog stuff. these can be shared with x11 i think?

we can just update the title/labels for #933 and #936

keymapping issues (copy/paste not generating the correct keystroke of x11/wayland).

Yes should create an issue. I think it is for all ctrl shortcuts
