Partly, there's just a lot of unnecessary boiler plate. It's also possible to define combinations of arguments that make no sense (e.g. eArgRepeatPlus followed by eArgRepeatPlain...) but these are never checked since we just push_back directly into the argument definitions. This commit is step 1 of this cleanup - do the obvious stuff. In it, all the simple homogenous argument lists and the breakpoint/watchpoint ID/Range types, are set with common functions. This is an NFC change, it just centralizes boiler plate. There's no checking yet because you can't get a single argument wrong. The end goal is that all argument definition goes through functions and m_arguments is hidden so that you can't define inconsistent argument sets.
