const_source_location returning empty values where MRI does not

[nirvdrum]

I'm running into an issue booting Sorbet. It uses const_source_location to build up a path to the lib directory. This works fine on MRI as it returns the filename defining the module whereas TruffleRuby returns [].

I've narrowed down the TruffleRuby issue to a simple reproduction (placed in a file named bad.rb):

module T
  module Private
  end
end

puts T.const_source_location(:Private)

On MRI, I get:

> ruby -v bad.rb
ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [arm64-darwin21]
bad.rb
2

On TruffleRuby, I get:

> jt ruby -v bad.rb
truffleruby 23.0.0-dev-71f07786*, like ruby 3.1.3, GraalVM CE JVM [aarch64-darwin]

I've looked at the issue briefly and it's due to the constants not having associated source sections. In that case, we have const_source_location return [].

This is an easy fix (#2835), interestingly we already recorded the SourceSection on RubyModule itself for interop, which is something Ruby doesn't have a way to query, but we missed to pass a node/SourceSection to setConstantInternal().

Great. I was planning to pick this one up. I was hoping it was easy, but feared it might require parser changes.
