Jake Hillion 333447a736 tests: add ClangTypeParserTest 
Currently there is no testing for ClangTypeParser even though it's used in
production. This is because adding integration tests is very hard: they require
testing the build time behaviour at runtime, or else they'd be build failures
intead of test failures. There's a PR available for integration tests but it's
incomplete.

In contrast ClangTypeParser can be sort of unit tested. This follows the
structure of `test/test_drgn_parser.cpp` with some differences. There is a
tonne of boilerplate for setting up the Clang tool, and this set of testing
operates on type names instead of OID functions. The new tests are also
incredibly slow as they compile the entire `integration_test_target.cpp` (which
is huge) for every test case. I don't think this is avoidable without
compromising the separation of the tests somewhat due to the way Clang tooling
forces the code to be structured.

Test plan:
- Tested locally
- CI

Object Introspection is a memory profiling technology for C++ objects. It provides the ability to dynamically instrument applications to capture the precise memory occupancy of entire object hierarchies including all containers and dynamic allocations. All this with no code modification or recompilation!

For more information on the technology and how to get started applying it to your applications please check out the Object Introspection website.
