acio: detect crash during acio init due to RTSS/Afterburner and complain (#334)

## Link to GitHub Issue, if one exists
n/a

## Description of change
When an exception is caught during ACIO hook init, print a special
message to suggest the user to disable RTSS and MSI Afterburner, since
they are known to cause issues.

## Testing
Tried with RTSS enabled with High detection and with it disabled. Also
tried to crash the game a different way and check that the message is
not printed and the callstack is shown propeerly.
