moved non X16 specific variables and vector definitions from cx16 to cbm namespace.
...
This makes the naming consistent with the other cbm-like targets (c64, pet, c128). Only the x16 specific ones remain in the cx16 namespace, such as cx16.KEYHDL
Probably the most impactful is the move of cx16.CINV to cbm.CINV
