[test] Delete some xfailed lldb-mi tests

This is a first pass at removing some lldb-mi tests which have been
xfailed and unmaintained for a while. We have open PRs for most of these
tests already. I've opened up the following additional PRs:

  llvm.org/PR36739 - lldb-mi driver exits properly
  llvm.org/PR36740 - lldb-mi -gdb-set and -gdb-show
  llvm.org/PR36741 - lldb-mi -symbol-xxx

The motivation here is to address timeout and pexpect-related issues in
the test suite. This was discussed on lldb-dev in the thread: "increase
timeout for tests?".

After this change, the lldb-mi tests seem to be in better health (on
Darwin at least). I consistently get:

Expected<SymbolMap> (if given a set of names) or an Expected<JITEvaluatedSymbol>

AsynchronousSymbolQuery for the given names, applies that query to each VSO in

threading is enabled then the materialization function object can be used to

[SymbolFilePDB] Rewrite ParseTypes method

Summary:
The types for the compiland's children are parsed when parsing types for a PDB compiland. Global types also need to be parsed but unfortunately PDBs do not have compiland information about each global type. So we parse them all on the first call to ParseTypes.

If a sc.function is provided then parse the types for that function. Otherwise parse the types for the overall sc.comp_unit.

The ParseTypes method can be very slow if a program has a long list of compile units containing needed modules. Debugging clang-cl with lldb will show the problem.
