Refactoring breakpoints to not use the `g_dap` reference. Instead, when a breakpoint is constructed it will be passed a DAP reference that it should use for its lifetime. This is part of a larger refactor to remove the global `g_dap` variable to allow us to create multiple DAP instances. --------- Co-authored-by: Pavel Labath <pavel@labath.sk>
