This patch adds a new variety of driver to Dexter, allowing it to work with DAP-based interfaces for debuggers. The first concrete instance of this is implemented in this patch, adding support for an `lldb-dap` debugger. This is functionally very similar to the existing LLDB debugger support*, but uses lldb-dap as its executable instead of lldb. This has been tested successfully against the existing feature_test suite, and manually tested against some other inputs; support is essentially complete, although any further DAP-based debuggers may require additional hooks inserted into the base class to deal with any idiosyncrasies they exhibit (as with the several that have been inserted for lldb-dap). NB: There are some small differences resulting from differences between lldb-dap's use of the lldb API and Dexter's use in its lldb driver; one small example of this is when evaluating variables, lldb-dap will try to first use `GetValueForVariablePath` and fallback to `EvaluateExpression` if necessary, while Dexter will always use `EvaluateExpression`; these can give slightly different results, resulting in different output from Dexter for the same input.
