Imports a custom-built copy of Klaus Dormann's 65C02 test, with only 65816-compatible parts.

Thereby fixes another couple of 65816 issues — BRK(, etc) not clearing the decimal flag, and `TRB d` being mismapped.

Oric Mist seems to use that format, so some of these now exist out in the wild.

Adds the 65816 as an in-code option for Oric emulation.

This also means it'll be exposed via the SDL build, but that's okay.

Declares address-bus sizes formally.
...
This allows me to fix the final two implicit conversion warnings, albeit that it would have been nice to find a templatey way just to get the type directly from the declaration of `perform_bus_operation`.

Chasing those down, it looks like flags were wrong for PLB and PLD. So it's official: warnings help.

Ensures intended 65816 exception behaviour.
...
i.e. the relevant micro-op sequence exists, and its operation isn't lost. Also sets the 65816 by default to jump straight into power-on, not to execute an instruction first. That shouldn't make a functional difference, but it makes debugging easier because it makes startup fully deterministic.
