fix: ImHex hangs when pressing F5 while in a breakpoint (#1920)

### Problem description
fix: pressing F5 (start pattern execution ) while being in a break point
hangs ImHex.


The reason for hanging ImHex was that the shortcut procedure was not
checking if the pattern was already running, and it attempted to start
another one. This makes ImHex wait indefinitely for a lock to be
released

### Implementation description

To fix the hanging of ImHex we check the runtime for current evaluation
and if detected we stop it. In all cases the evaluation is started
again.
