Pete Bacon Darwin df92abc60a refactor(compiler): make I18MetaVisitor stateless (#33318)
This commit cleans up the I18MetaVisitor code by moving all the
state of the visitor into a `context` object that gets passed along
as the nodes are being visited. This is in keeping with how visitors
are designed but also makes it easy to remove the
[definite assignment assertions](https://mariusschulz.com/blog/strict-property-initialization-in-typescript#solution-4-definite-assignment-assertion)
from the class properties.

Also, a `I18nMessageFactory` named type is exported to make it
clearer to consumers of the `createI18nMessageFactory()` function.
