Debugger: read_memory_32 initiates TLB_refill exception on reading invalid memory

[flagrama]

The full offending code path is located at the end of this message.

If you use the debugger to read any memory that isn't "valid" the virtual_to_physical_address function forces a TLB_refill_exception to the emulator. As all of the "readmemory" functions use read_memory_32 they are all affected by this issue. I believe that the `writememory` functions are also affected by this, however I have not tested it.

The debugger should never be causing exceptions to occur. Either the debugger needs to be special case opted out of the passing of the exception, or the debugger needs to use its own memory handler that simply reads the data.

@Gillou68310 Wanna just add a ignore tlb param or ifdef the prototype for DBG or dupe code?
