bf5ed98f35 Generalise 65c02 behaviour. 
Partly to convince myself:
1. this change alters behaviour of `CycleAddXToAddressLowRead`
2. which affects only `AbsoluteXw` and the 65c02-specific `JMP (abs, x)`;
3. `AbsoluteXw` is then used only by `AbsoluteXWrite` and `AbsoluteXReadModifyWrite`;
4. `AbsoluteXWrite` is used for abs, x addressing by `SHY`, `STA` and `STZ`;
5. `AbsoluteXReadModifyWrite` is used for `ASL`, `ASO`, `ROL`, `RLA`, `LSR`, `LSE`, `ROR`, `RRA`, `DEC`, `DCP`, `INC` and `INS`.

... though many of the latter are replaced by instance of `FastAbsoluteXReadModifyWrite` for the 65c02 which don't include a dummy
access at all if the page boundary is crossed so the issue is moot.

d12316dfcf Change phase from int to uint8_t 
output_colour_burst expects a uint8_t so may as well make that clear.

cd4498a36a Improve macOS SDL Macintosh video & Apple II colors 
Hacks in AppleII/Video.cpp, AppleII/Video.hpp, and Macintosh/Video.cpp
assume that building on macOS means building for Metal unless
IGNORE_APPLE is defined. By defining this in the macOS SDL build,
Macintosh video is now sized and positioned correctly and Apple II
colors are now just as wrong as they are on other OpenGL builds instead
of being wrong in a unique way.

See #872
