The v810 llvm fork comes with a working version of lldb. This PR implements the remote debugger protocol used by lldb and gdb. With these two tools combined, we have source-level debugging support for Virtual Boy games written in C, C++, or rust!

Also includes more build optimizations, to hopefully keep the emulator running in real time even when lots of breakpoints/watchpoints are enabled. And some boring application lifecycle fixes.
