A few cleanups.

- Cleanup the blueprint file a bit.
- Fix the formatting in DwarfMemoryTest.cpp.
- Fix the misnamed test MemoryBuffer.cpp to MemoryBufferTest.cpp.
- Add a function to find the location of the test files so it's not
  necessary to run the test in the same directory as the test files.

Bug: 23762183

Test: Builds and unit tests pass.
