[clang-tools-extra] [clang-doc] Avoid reading files in unit tests (PR #141269)

[Paul Kirth via cfe-commits]

https://github.com/ilovepi created https://github.com/llvm/llvm-project/pull/141269

In #138062 it was brought up that this was an anti-pattern. We'll need
to Migrate all of the mustache unittests to lit tests, and disable them
until tool support lands.
