Import Dexter to debuginfo-tests

Dexter (Debug Experience Tester) is a test-driver for our debug info
integration tests, reading a set of debug experience expectations and
comparing them with the actual behaviour of a program under a debugger.
More about Dexter can be found in the RFC:

  http://lists.llvm.org/pipermail/llvm-dev/2019-October/135773.html

and the phab review in D68708. Not all the debuginfo tests have been
transformed into Dexter tests, and we look forwards to doing that
incrementally.

This commit mostly aims to flush out buildbots that are running
debuginfo-tests but don't have python 3 installed, possibly
green-dragon and some windows bots.

-These are debug info integration tests similar to the ones in the parent
-directory, except that these are designed to test compatibility between clang,
-lld, and cdb, the command line debugger that ships as part of the Microsoft
-Windows SDK. The debugger command language that cdb uses is very different from
-gdb and LLDB, so it's useful to be able to write some tests directly in the cdb
-command language.
