Stacked on WordPress#7555. Trac ticket: https://core.trac.wordpress.org/ticket/62057

This is the same change as 62057.6.patch on the ticket, as a single commit on top of ticket/62057 so it can be reviewed or merged as a delta.

What changes

• One query path. The direct autosave query runs for every request; author only adds author__in. Without author, the collection previously still loaded every revision through wp_get_post_revisions(), which is what core's editor preload requests today.
• post_name__in instead of name, so the query isn't singular.
• suppress_filters set to true, preserving the isolation the old get_posts() path had. With false, a global posts_where/posts_orderby filter applied to the author lookup.
• The per-author dedupe applies to both paths, so scoped and unscoped responses agree.
• @since 7.3.0 on get_items() and get_collection_params(); stale per_page wording removed from a test docblock.
• New test test_get_items_is_isolated_from_query_filters (unscoped and author scoped).

Before / after

Measured at svn r64336. Retained memory is the memory_get_usage() delta across one rest_do_request() with caches flushed, one PHPUnit process per row. Each post has 3 autosaves plus N ordinary revisions, about 200KB each. Single run per row.
