[clang-doc] Add index in each info html file

[DiegoAstiazaran]

Summary

An index structure is created while generating the output file for each info. This structure is parsed to JSON and written to a file in the output directory. The html for the index is not rendered by clang-doc. A Javascript file is included in the output directory, this will read the JSON and insert HTML elements into the file.

Wrong indentation?

Fix format of index.js file

Yes, clang-format "missed" that because I forgot the semicolon in the previous line.
Thanks, it has been fixed.

Why is this implementation in the generic Generator? It's fairly HTML-specific -- neither of the other generators are able to parse and include Javascript (since this does include the var JsonIndex bit).

Can we move this to ClangDocMain.cpp right above where the function is called? That's where most of these types of status updates are.

Moved serialization of Index to HTML generator.

Moved to HTMLGenerator.cpp; it was there because I was first writing a JSON file which could be used for any generator.
