Herald added a project: clang.

With this patch the `findReferences` API will return Xref for macros.
If the symbol under the cursor is a macro then we collect the references to it from:

1. Main file by looking at the ParsedAST. (These were added to the ParsedAST in https://reviews.llvm.org/D70008)
2. Files other than the mainfile by looking at the:
  - static index (Added in https://reviews.llvm.org/D70489)
  - file index (Added in https://reviews.llvm.org/D71406)

This patch collects all the xref from the above places and outputs it in `findReferences` API.
