[kbn-grid-layout] Flatten grid layout (#218900)

Browse source 
Closes https://github.com/elastic/kibana/issues/216096

## Summary

This PR accomplishes two main things:
1. It flattens out how grid elements are rendered, which means that
embeddables no longer re-mount when dragged between sections and
2. It allows panels and sections to be "intermixed" on a **single**
level (i.e. you can only drop a section header between panels if they
are **not** in a section)

Since this was a **major** rewrite of the grid layout logic, I also took
some time to clean up the code - this includes removing
`proposedGridLayout$` (since this added two sources of truth, which was
causing issues with the DOM becoming out-of-sync with the layout object;
however, this also caused
https://github.com/elastic/kibana/issues/220309) and unifying on the use
of "section" rather than "row" (since it was confusing that we were
using "row" for both the grid row number and the section ID).

> [!NOTE]
> Reminder that, since collapsible sections aren't available in
Dashboard yet, you must test this PR in the `grid` example app (by
running Kibana with `yarn start --run-examples`).
