Auto merge of #37607 - dns2utf8:doc_grammar, r=alexcrichton

Browse source 
Fix grammar verification

 * Use make check-lexer to verify the grammar.
 * Extend grammar/README
 * Add make clean-grammar rule
 * Add target check-build-lexer-verifier to make tidy, so it will build the verifier with every build and catch future errors

This is the continuation of #34994
