[pseudo] Support annotations in the grammar.

This patch adds annotations in the bnf grammar.

Annotations (which has a form of `[key1=value;key2=value]`) specify extensions,
which can be associated with a grammar symbol or a rule.
It provides a way to inject custom code into the general GLR parser, we will
use it for error recovery and  more freely control the reduce actions.

This patch is part of D126536 <https://reviews.llvm.org/D126536>, focusing on the grammar level.
