tags: Add regex for context_lock_struct

With the introduction of compiler context analysis (LLVM
ThreadSafetyAnalysis) the struct definition of various locks get
wrapped in a macro. This hides them from tags based navigation,
although clangd/LSP sees right through it and works as expected.

Add a regex to the tags script to help it along.
