Handle mapped program memory segment aliasing properly, on WCH RISC-V targets

Browse Source 
- Added `program_segment_key` target config param, to allow the user to specify the desired program memory segment
- Added the ability to resolve the currently aliased segment, by means of probing the mapped segment
- Added program counter transformation, when the mapped segment is aliasing a foreign segment
- Other bites of tidying
