io: fix bi2x_hook implementation in various games (#522)

Browse Source 
## Link to GitHub Issue, if one exists
similar issue as #499

## Description of change
Fix broken bi2x_hook implementations that did not properly allocate I/O
buffers with correct sizes.

People keep copy-pasting other implementation that allocate 0 bytes of
memory, but we run the risk of memory corruption or/or game crashes if
we keep doing this.

We've seen some mystery crashes with CCJ for example, maybe this will
fix that.

While I'm here, implement SOCD cleaner for Polaris Chord.

## Testing
Tested I/O menu with CCJ, play through tutorial (didn't test matches)
Tested GWDelta (test menu and a few songs in guitar)
Tested PC (played a credit)
Tested QKS (still can't get past the title screen)
