rawinput: deal with high poll rate devices, use 3x3 for default for rb touch emu (#796)

## 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.
