chunk: split writing side-effects into own function
...
split writeConstant() into that and writeConstantRaw() for the places
where we don't want OP_CONSTANT written as well.
this caused a bug where doing `"some const string" + x` would cause an
unecessary OP_CONSTANT to be added for the x variable and would cause
the wrong result to be given.

the java part would still fuck me up since it lies on OOP stuff
that zig doesnt provide, so i'm skipping towards the C part of the book
which will hopefully be more understandable from a zig perspective.
