chore(interpreter): move memory access functions to computer
...
This is mainly to ease the usage of memory access functions, meaning
leaner access of memory with general resulution of memory accesses via
the MemoryIndex struct.

chore(interpreter): rewrite displacement memoryindex logic
...
Previously, the displacement for a MemoryIndex was directly interpreted
and saved as a signed value.
Change this to the normal unsigned ImmediateOperand version to allow
for more flexible usage of this struct for general memoryaccess (future
commit) and just interpret the displacement member as signed, only when
being interpreted as such (memory access, display, ....

fix: align pointer parsing with spec
...
Previously pointer parsing was completely wrong.
Now split into Pointer32 for immediates with
segment;offset and Pointer16 for short jumps, which
use DS or ES as segment and the Pointer16 value
as offset.
