In `clang-tools-extra\clang-doc\tool\ClangDocMain.cpp`, there is a function, `getDefaultAssetFiles` that tries to find the location of 
`<build dir>\share\clang-doc\index.js`, but fails. This is because there are alternate configurations in setting up the llvm project, and executables in different locations may be run. In some cases, executables are built and run in this location:
`<build dir>\bin\<executables>`
and in other cases, this location:
`<build dir>\[Debug | Release]\bin\<executables>`

The locator assumed that the executable that is running was in the first example above, and in the case that an executable under Debug / Release was run, the index.js file wouldn't be found.
This PR adjusts the locator to be agnostic to either scenario described above, and ascends an extra directory if the Debug directory is detected.
