Grid header/footer rewrite: add partial shared state support (#13334)

Currently supported:
* Adding and removal of header and footer rows
* Header is single-row by default
* Footer is zero-row by default
* Text captions
* Showing and hiding the whole header or footer
* Passing captions and visibility in shared state

TODO:
* Column spanning
* HTML content
* Widget content
* Component content
* Sorting/Indicators
* Server side API
* Rest of shared state handling
