gdbstub: move breakpoint logic to accel ops As HW virtualization requires specific support to handle breakpoints lets push out special casing out of the core gdbstub code and into AccelOpsClass. This will make it easier to add other accelerator support and reduces some of the stub shenanigans.

gdbstub: Use vaddr type for generic insert/remove_breakpoint() API Both insert/remove_breakpoint() handlers are used in system and user emulation. We can not use the 'hwaddr' type on user emulation, we have to use 'vaddr' which is defined as "wide enough to contain any #target_ulong virtual address". gdbstub.c doesn't require to include "exec/hwaddr.h" anymore.

gdbstub: move guest debug support check to ops This removes the final hard coding of kvm_enabled() in gdbstub and moves the check to an AccelOps.
