[lldb] Fix Lua/watchpoint_callback.test on Apple Silicon 

As Pavel pointed out, on Apple Silicon "b main" stops at a point after
the variable has already been initialized. This patch updates the test
case to avoids that. I've also split the test into separate files so its
easier to reproduce the individual scenarios without having to build any
shared state.
