UI: deduplicate code for Copy To Selected and Alt-button tweaking

This resolves an old TODO to deduplicate code in copy_to_selected_button
& ui_selectcontext_begin.
This is also in hindsight of adding id-property support [incl. Geometry
Nodes modifier properties] for this in the next commit.
No behavior change expected here.
