Add support for "Entity browser" displays

Problem/Motivation

The Views filters summary "x" and "Reset" buttons do not work when used with Entity Browser displays. This is because of how the data-exposed-form-id property is constructed. For standard displays (e.g., Page), exposed form ID it is built like:

<form id="views-exposed-form-<VIEW_ID>-<DISPLAY_ID>...">

However, for Entity Browser displays the situation is different. Entity Browser embeds the View’s exposed filters inside its own form (no separate <form id="views-exposed-form-...">). The Entity Browser form ID looks like:

<form id="<DISPLAY_ID>...">.

This situation is not covered on Views Exposed Filters Summary.

Steps to reproduce

Configure View with display Entity Browser, with Views Exposed Filters Summary.

Proposed resolution

Detect Entity Browser displays and generate data-exposed-form-id correctly.

Remaining tasks

Review.
