Emulator

Currently, all the debug widgets have different behavior when stopping emulation:

• The Code widget clears out instructions and associated data but updates the address to where the PC was when stopped.
• The Branch Watch Tool leaves everything how it was.
• The Registers widget leaves everything how it was the last time it updated. Scrolling shows the entire state.
• The Threads widget clears out everything except for the state info.
• The Watch widget is not interactable. It shows the watches that existed the last time it updated.
• The Breakpoints widget is cleared.
• The Memory widget leaves everything how it was the last time it updated (either from being paused or having auto-update enabled). Scrolling shows dashes in all memory locations that weren't visible at that time.
• The Network widget's socket table and SSL context are not interactable and show the state from the last time they updated.
• The JIT widget is cleared, though it maintains the state of whether or not it is profiling.

These should all be completely cleared to the same state as before starting emulation. (I'm not including the Assembler widget, as it's basically just a text editor with no connection to the game being emulated.)
