If the default target and host triple don't match then print the following
message when the lit test runs:
Forcing dexter tests to use host triple {HOST_TRIPLE}.
If we can't target the host arch then, when lit runs, we mark
the dexter test directories as UNSUPPORTED and print the message:
Host triple {HOST_TRIPLE} not supported. Skipping dexter tests in
the debuginfo-tests project.

This is checking the version of Python used to run lit, which is not
necessarily the same as the version used to run the dexter tests. If
the tests are run via the build/bin/llvm-lit[.py] helper script, then
that is likely to pick up whatever version of Python is on PATH.
Conventionally, this will find Python 2. CMake already checks that
Python 3 is in use and puts the path to it in the lit site config, so
this check is redundant, and Python 3 will ultimately be used to run
dexter.

This reverts commit cb935f3456.
Discussion in D68708 advises that green dragon is being briskly
refurbished, and it's good to have this patch up testing it.
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.
