## Description of change
Change the usage pattern for Card Manager UI.
### Previous behavior
Previously, it was a list of cards that you select, and click a button
to insert as P1 or P2.
This is fine, but users got confused when they pressed `Insert Card`
overlay key and got a different card inserted, or when auto-insert
didn't work as expected.
Additionally, if you play a game without continue (IIDX/DDR for
example), then it's cumbersome to bring up the overlay and click on
insert card every time.
### New behavior
Insert Card overlay now lets you pick a card and *slot* it into P1 or P2
side.
From that point on, the slotted card number is used as the override,
replacing what was previously passed to `-card0` or `-card1`. This means
that `Insert Card` button and auto-insert will pick up the new card and
use that instead.

## Testing
Tested 1p-only game (popn) and 2p games (DDR, IIDX).

## Description of change
Update ImGui to `v1.91.4`. We can't update to `v1.91.5` or newer just
yet because impl_spice depends on the old IO model of ImGui which got
removed in `v1.91.5`.
We also can't update the DX9 renderer right now, because at some point
overlay breaks in TDJ (and only in TDJ...)
Enable the new debug logging functionality in ImGui. Add a button in
overlay to toggle debug log window.
Fix some minor bugs spotted by the new ImGui debug log: mismatched API
calls, font loading issues.

## Testing
In progress.
