Interrupt callback rationalization
- Make CPUs pass interrupt return PC as a second argument to standard_irq_callback
- Add interrupt return PC to "Stopped at interrupt" message produced by debugger 'gint' command
- Add messages to trace logs whenever interrupts are accepted
- Attempt to step over interrupt routines for applicable debugger commands
- Eliminate standard_irq_callback_member wrapper method
- Update many CPU cores to invoke standard_irq_callback at the start of or during interrupt processing, rather than at the end or when the input line changes
- Remove IRQ callbacks for some input lines that never cause interrupts
- mb88xx, mcs48: Add IRQ callbacks for internal interrupts
