[Fizz] Support special HTML/SVG/MathML tags to suspend (#21113)
* Encode tables as a special insertion mode

The table modes are special in that its children can't be created outside
a table context so we need the segment container to be wrapped in a table.

* Move formatContext from Task to Segment

It works the same otherwise. It's just that this context needs to outlive
the task so that I can use it when writing the segment.

* Use template tag for placeholders and inserted dummy nodes with IDs

These can be used in any parent. At least outside IE11. Not sure yet what
happens in IE11 to these.

Not sure if these are bad for perf since they're special nodes.

* Add special wrappers around inserted segments depending on their insertion mode

* Allow the root namespace to be configured

This allows us to insert the correct wrappers when streaming into an
existing non-HTML tree.

* Add comment

The error code system substitutes React's error messages with error IDs to provide a better debugging support in production. Check out the blog post here.

  • codes.json contains the mapping from IDs to error messages. This file is generated by the Gulp plugin and is used by both the Babel plugin and the error decoder page in our documentation. This file is append-only, which means an existing code in the file will never be changed/removed.
  • extract-errors.js is an node script that traverses our codebase and updates codes.json. You can test it by running yarn extract-errors.
  • transform-error-messages is a Babel pass that rewrites error messages to IDs for a production (minified) build.
