Always use 1 thread while using interpreter mode

Browse source 
Interpreter mode (as opposed to the regular speedy recompiler mode) is expected to be primarily used for debugging, and thus should be used with one core. However, unlike the game profile option, the `--force-interpreter` launch parameter didn't limit the amount of cores used to 1. This commit fixes that issue, alongside an additional temporary fix that helps situations where a debugger trap instruction gets hit by two threads simultaneously. Eventually this should be replaced with a more advanced approach that'd freeze other threads while stepping.
