rawinput: deal with high poll rate devices, use 3x3 for default for rb touch emu (#796)
## Link to GitHub Issue or related Pull Request, if one exists n/a ## Description of change Two changes: 1. Handle all HID events in `WM_INPUT` and not just the first one. This only really affects 4000Hz / 8000Hz HID devices. 2. Go back to `3x3` as the default for rb IR touch emulation and remove `1x1` as an option as it does not perform as well as I expected. ## Testing
