overlay: migrate configurator UI from ImGui Columns to Tables (#282)

## Link to GitHub Issue, if one exists
n/a

## Description of change
`ImGui::Columns` is a deprecated component with many issues. Migrate
Buttons/Analog/Overlay/Lights/Options... tabs to the new table API.
Clean up some UI elements around it to reduce clutter.

Note: there are still other usages of Columns API (MIDI debug output,
ACIO viewer, window manager) but no one hardly ever sees those.
Eventually they will need to be migrated if ImGui ever drops support for
them.

## Compiling
👍 

## Testing
Testing all games in spicecfg and overlay.
