pcsx2 Debugger: Fix possible recursion loop when pause-on-tlb-miss is enabled

Description of Changes

The comment says it all. Essentially the pause handler in the debugger could cause a tlb miss, which would pause the VM again, which would call the pause handler in the debugger (you see a pattern?)

Rationale behind Changes

Patches the issue where resetting with pause-on-tlb-miss and the debugger enable could crash

Suggested Testing Steps

Enable pause-on-tlb-miss, open the debugger, and reset a bunch of times and see if PCSX2 crashes.

Fixes #11594

Can you show error and backtrace?

I fixed the recursion, but you're right, the crash is still there.

The backtrace is quite odd, it's crashing inside of Qt. I'll have to further investigate.

I don't have a crash log.
