Make Register16 a class, rather than struct. Tricky, but a bit faster than before.

Help out callers using Register16 arguments a little: Don't always require the ".Word" property to be passed.

Resurrect the Register16 class. This (or something *very* much like it) is going to be necessary to add a Z80 emulator (reference access to the high/low parts of 16-bit registers).

A few small consistency updates:
...
1) Drop Get/SetPagedByte in favour of normal BusRead/Write
2) Tidy some "using" statements
3) More "expression body" usage, if possible
4) Use field initialisation, rather than construction, if possible
5) Correct IntelProcessor register set/get methods (there were remnants of "copy pasta" code)
