Move debug-related stuff from base to the base/debug directory and use the

base::debug namespace.

This splits apart debug_util into base/debugger and base/stack_trace
There are still two functions in debug_util that I'm not sure what to do with.
Since this uses the base::debug namespace, I removed the functions in
debugger.h from the static class and just made them free functions in the
namespace.

TEST=it compiles
BUG=none
