macos: menu item symbols for Tahoe

This is recommended for macOS Tahoe and all standard menu items now have
associated images. This makes our app look more polished and native for
macOS Tahoe.

For icon choice, I tried to copy other native macOS apps as much as
possible, mostly from Xcode. It looks like a lot of apps aren't updated
yet. I'm absolutely open to suggestions for better icons but I think
these are a good starting point.

One menu change is I moved "reset font size" above "increase font size"
which better matches other apps (e.g. Terminal.app).
