Debugger: Replace libuv with platform-specific connection code

Remove libuv usage from CMake debugger. Libuv has an async io model
and cppdap uses a sync model, so an extra thread and a buffer copy
were necessary to match semantics. In order to eliminate those
costs this commit implements the IO using platform specific APIs.
