[clang-tools-extra] [clangd] Enable config files by default in clangd-indexer (PR #228683)

[via cfe-commits]

https://github.com/Fil-Den created https://github.com/llvm/llvm-project/pull/228683

This is a continuation of #214951. It enables config file support by default. The change is small, so it can be easily reverted if needed.
