[llvm-branch-commits] [clang-tools-extra] [clang-doc] Implement setupTemplateValue for HTMLMustacheGenerator (PR #138064)

[Paul Kirth via llvm-branch-commits]

https://github.com/ilovepi created https://github.com/llvm/llvm-project/pull/138064

This patch implements the business logic for setupTemplateValue, which
was split from #133161. The implementation configures the relative path
relationships between the various HTML components, and prepares them
prior to their use in the generator.
