802d4631 - [clang-doc] Update lookup routines for consistency (#190043)

[clang-doc] Update lookup routines for consistency (#190043) When filtering is enabled, its possible an Info doesn't have a Parent USR. Use `find()` to safely handle that case. Additionally, I noticed the comparison code for the index poorly reimplemented the existing comparison from StringRef. We can just use the one from ADT.
