gitignore: update

The .cache and compile_commands.json is used by popular source crawling and
indexing clang tools which in turn may be integrated with source code editors.

We may reuse the .cache directory for for other caches and temporary
files.

The /doc/.ikiwiki and /public are related to the ikiwiki.
