Moves the highlighting docs from the deprecated 'Request Body Search'
chapter to the new subpage of the 'Run a search chapter' section.
No substantive changes were made to the content.
Changes:
* Adds additional examples to the `Search a data stream` section of
`Use a data stream`
* Updates existing search docs to make them aware of data streams
This PR adds a section to the new 'run a search' reference that explains
the options for returning fields. Previously each option was only listed as a
separate request parameter and it was hard to know what was available.
Reworks the `from / size` content to `Paginate search results`.
Moves those docs from the request body search API page (slated for
deletion) to the `Run a search` tutorial docs.
Also adds some notes to the `from` and `size` param docs.

**Goal**
Create a top-level search section. This will let us clean up our search
API reference docs, particularly content from [`Request body search`][0].
**Changes**
* Creates a top-level `Search your data` page. This page is designed to
house concept and tutorial docs related to search.
* Creates a `Run a search` page under `Search your data`. For now, This
contains a basic search tutorial. The goal is to add content from
[`Request body search`][0] to this in the future.
* Relocates `Long-running searches` and `Search across clusters` under
`Search your data`. Increments several headings in that content.
* Reorders the top-level TOC to move `Search your data` higher. Also
moves the `Query DSL`, `EQL`, and `SQL access` chapters immediately
after.
