Fixes#512
## Description of change
Fix digital wailing not being recognized consistently.
Also address the fact that wailing was completely broken when lefty mode
was on. This requires a new option that the user needs to check off in
the configurator since we can't magically guess if the user is holding
the guitar in lefty mode.
- [x] fix downward wail
- [x] digital lefty mode
- [x] implement all of this for arena model i/o
- [x] test dx cab 2p
- [x] lefty toggle in overlay
- [x] fix analog not working for 2p guitar
- [ ] analog lefty mode?
## Testing
Checked GW and GW Delta

#452
## Description of change
(Another extension of #450)
Merged the old threading implementation into the current backfill
implementation because it was showing signs of having slightly better
timing performance. The following description is taken from the
strikethrough text from the referenced PR above:
>When the module is booted, it counts how many times
ac_io_mdxf_update_control_status_buffer was called in the first three
seconds, then calculates the approximate refresh rate of the current
game instance. If the refresh rate is under THRESHOLD_REFRESH_RATE
(120Hz), a low-priority thread dedicated to inserting polls into the
ring buffers is started and run at THREAD_REFRESH_RATE_HZ (125Hz).
Combined with the polls inserted by the main arkmdxp4 thread and
rawinput real-time events, the 125Hz update cadence is enough to bring
the span of poll history represented by the ring buffers closer to
parity with what arkmdxp4 expects.
The default mode is `THREAD_MODE` but can be switched to `BACKFILL_MODE`
(which could possibly be made as a `spicecfg` option).
There was also a fixed bug in the `ac_io_mdxf_get_control_status_buffer`
function, which should not have been writing to the `head` pointer. This
was allowing for an edge case situation where the `head` pointer was
advanced in another thread then rewound back to the previous `head` in
this thread. The real implementation only reads the pointer and returns
it.
## Testing
- Logged the ring buffer states after many iterations and verified
regular structure
- Same playtesting as the prior PRs

#452
## Description of change
- Extension of #450
- Moved the call to `arkGetTickTime64()` outside the update function to
bring the timestamps closer to real-time
- Changed the update function to only call `getState()` if called from
`rawinput`, otherwise just fill the ring buffer entries with the last
known state
- Changed the update function to only write one ring buffer entry if
called from `rawinput`
- Moved the call to `mdxf_poll()` within `rawinput.cpp` outside the loop
that iterates over all devices
## Testing
- Logging was done to verify the span of poll history covered by each
request for 7 ring buffer entries was ~28ms, as the game expects
- Observed some improvement in timing precision since the prior
implementation
## Context
In the real implementation of `ac_io_mdxf_update_control_status_buffer`,
it doesn't actually add entries to the pad state ring buffers (it only
marks the head entry as the "last consumed" entry), and `arkmdxp4.dll`
expects the ring buffers to be updated at regular intervals inside
`libacio2.dll` at ~250Hz per player. Instead, in the emulated version,
the updates happen in this function and that regular interval is
established internally using the game's refresh rate (60Hz, 120Hz,
144Hz, etc.). This effectively locks the polling rate of pad input to
that refresh rate, which is quite low for pad input.
## Description of change
The polling rate lock was circumvented by calling
`ac_io_mdxf_update_control_status_buffer` as soon as the game receives
controller input in `rawinput.cpp`. A simple wrapper function
`mdxf_poll` was exposed so press and release events could be added to
the ring buffers in real time as they happen. After each controller
event in `rawinput.cpp`, `mdxf_poll` calls
`ac_io_mdxf_update_control_status_buffer` for each player, checking the
pad's current state and adding it to the ring buffer if it's changed
since the last call. This results in the 0 -> 1 (press) and 1 -> 0
(release) state transitions used for gameplay to be based only on the
real-time events inserted from `rawinput.cpp`, while leaving the rest of
the entries generated from the main `arkmdxp4.dll` thread as "padding"
the game expects (I actually tried reducing the ring buffers to *only*
write entries on state transitions, but it broke gameplay, which means
the game still depends regular reporting of the pad state). Here's an
example of how a ring buffer would look if an arrow was pressed at some
time 32ms (assume 165Hz game refresh rate, ~6ms updates):
```
Old (only frame updates):
1 | 36ms
0 | 30ms
0 | 24ms
0 | 18ms
0 | 12ms
0 | 6ms
0 | 0ms
```
The game only sees the press event at time 36ms on frame update, so time
36ms is assigned to the press time of that arrow (4ms later than the
real press time).
```
New (frame updates + event updates from rawinput.cpp):
1 | 36ms
1 | 32ms <- from rawinput.cpp
0 | 30ms
0 | 24ms
0 | 18ms
0 | 12ms
0 | 6ms
```
The game sees the real press time 32ms on frame update, so the correct
press time 32ms is assigned.
## Testing
- Played on various refresh rates and verified the controller input
remains highly responsive.
- Inspected the ring buffers with a debugger and verified entries for
press and release events from `rawinput.cpp` were correctly being added
for their respective players.

## Description of change
For HID device descriptor, use the "W" version of Windows API, and make
sure UTF-8 is being used throughout since that's the only format IMGUI
supports.
Before this change, non-Latin characters would have shown up as `HID ???
?????` for a mouse, for example.
Due to the way ImGui loads fonts, only the following languages are
supported:
* Simplified Chinese
* Cyrillic
* Japanese
* Korean
* Thai
* Vietnamese
## Testing
Tested various combination of Windows UI language and non-Unicode
language.

Fixes#364
## Description of change
The game attempts to hook raw input, but raw input API can only be used
by one window per process. Hook `RegisterRawInputDevices` and prevent
the game from registration for raw input notifications.
## Testing
Tested that HID keyboard works with `Bind` option.

Fixes#139
## Description of change
Add an option for detecting window focus when accepting input.
The new default will be to have the following:
* naive bindings will check for window focus
* rawinput binds are not affected, will continue to be accepted
regardless of focus
Other options (always / never choices) can be picked by the user to
tweak the behavior if needed.
Clean up usage of `0xff` constant to represent invalid naive vkey.
## Testing
Still in progress, especially in regards to performance.
On a i7-9700 system, 10000 calls to `superexit::has_focus()` takes
250-350 microseconds, so this should not be a big deal at all.
