The current rdoc/rd/inline_parser.rb and rdoc/rd/block_parser.rb have require "racc/parser" for external dependency. We should avoid to depend it for RD parser.

Note: racc/parser still have racc/info. We also embed it to racc/parser.

For those who wonders how this impacts RDoc license, there should be no impact IMHO, because Racc explicitly allows to use the embedded parser with whatever license:

https://github.com/ruby/racc/blob/5eb07b28bfb3e193a1cac07798fe7be7e1e246c4/lib/racc/parser.rb#L8-L10

And FTR, maybe this could be mentioned somewhere in LEGAL.rdoc

In ruby/rdoc#1019 RDoc starts embedding Racc. But
Racc in Ruby 3.3 will not be a default gem anymore, which requires explicit
declaration in Gemfile.
