Work around race condition when stepping (CpuRunning still true in
Sh4Executor::Step() on emu thread since Step() hasn't be called yet in
main thread).
Don't advertise vCont commands that aren't supported.
Range stepping end is exclusive.
* Enabled GDB server, compile fix for MSVC, added GDB option to config
* GDB - 'vMustReplyEmpty' should not be explicitly handled, it is a test for how the target responds to unknown vpackets (which was incorrect)
* GDB wait for debugger option to allow debugging from bootstrap, and Event::Resume moved after renderer init so agent.interrupt() can pause the renderer
* Draw "Waiting for debugger", and fixed UI not rendering last frame before a state change
* Fixed GDB regs/mem endianness
