[SIM65] Support undocumented opcodes for 6502
...
This PR is mostly a complete rewrite of the emulator for 6502/65c02 opcodes.
It provides an easier to maintain implementation of the instructions, by using few macros rather than having hand-written code for each function.
All undocumented, previously missing opcodes for 6502 are also implemented.
The patch also includes a detailed documentation of those opcodes, for reference to developers.
This PR should fix one of the milestones listed here for the next version of CC65:

Replaced builtin macro packages with .mac files that are included like ordinary .inc files.
...
The benefits are:
- Independency of ca65 build from perl
- More transparent behaviour
