Deduplicate the code and use the same logic used to
calculate individual elements in `t->values_final[0]`.

Tool System: Use tapping Alt as a leader key to switch tools

Now tapping Alt prompts for a second input to switch tools.

Without this, boxes are unusable in header layouts as they
add vertical space which shifts the items out of the header.

WM: add utility to lookup a keymap item from an event

Useful for modal operators to be able to match events
against regular keymaps.

UI: add utility to show icons for the keymap item

This is useful for drawing keymap items into the header or status bar

While these icons are available directly,
mapping them from the keymap item isn't trivial.
