Streamlining media, part I.

The main goal here is to rearrange the media components in a modularized structure to support more linear workflows. This is that structure using the pre-existing workflows, which will be improved over the course of the next few commits.

This leaves a few pieces a bit rough around the edges: namely gallery editing and selecting a featured image.

The fine print follows.

----

'''Styles'''
* Tightened padding around the modal to optimize for a smaller default screen size.
* Added a light dashed line surrounding the modal to provide a subtle cue for the persistent dropzone (which is evolving into a power user feature since we now have a dedicated `upload` state).
* Add a size for `hero` buttons.
* Remove transitions from frame subviews (e.g. menu, content, sidebar, toolbar).

----

'''Code'''

`wp.media.controller.StateManager`
* Don't fire `activate` and `deactivate` if attempting to switch to the current state.

`wp.media.controller.State`
* Add a base state class to bind default methods (as not all states will inherit from the `Library` state).
* On `activate`, fire `activate()`, `menu()`, `content()`, `sidebar()`, and `toolbar()`.
* The menu view is often a shared object (as its most common use case is switching between states). Assign the view to the state's `menu` attribute.
* `menu()` automatically fetches the state's `menu` attribute, attaches the menu view to the frame, and attempts to select a menu item that matches the state's `id`.

`wp.media.controller.Library`
* Now inherits from `wp.media.controller.State`.

`wp.media.controller.Upload`
* A new state to improve the upload experience.
* Displays a large dropzone when empty (a `UploaderInline` view).
* When attachments are uploaded, displays management interface (a `library` state restricted to attachments uploaded during the current session).

`wp.media.view.Frame`
* In `menu()`, `content()`, `sidebar()`, and `toolbar()`, only change the view if it differs from the current view. Also, ensure `hide-*` classes are properly removed.
*

`wp.media.view.PriorityList`
* A new container view used to sort and render child views by the `priority` property.
* Used by `wp.media.view.Sidebar` and `wp.media.view.Menu`.
* Next step: Use two instances to power `wp.media.view.Toolbar`.

`wp.media.view.Menu` and `wp.media.view.MenuItem`
* A new `PriorityList` view that renders a list of views used to switch between states.
* `MenuItem` instances have `id` attributes that are tied directly to states.
* Separators can be added as plain `Backbone.View` instances with the `separator` class.
* Supports any type of `Backbone.View`.

`media.view.Menu.Landing`
* The landing menu for the 'insert media' workflow.
* Includes an inactive link to an "Embed from URL" state.
* Next steps: only use in select cases to allot for other workflows (such as featured images).

`wp.media.view.AttachmentsBrowser`
* A container to render an `Attachments` view with accompanying UI controls (similar to what the `Attachments` view was when it contained the `$list` property).
* Currently only renders a `Search` view as a control.
* Next steps: Add optional view counts (e.g. "21 images"), upload buttons, and collection filter UI.

`wp.media.view.Attachments`
* If the `Attachments` scroll buffer is not filled with `Attachment` views, continue loading more attachments.
* Use `this.model` instead of `this.controller.state()` to allow `Attachments` views to have differing `edge` and `gutter` properties.
* Add `edge()`, a method used to calculate the optimal dimensions for an attachment based on the current width of the `Attachments` container element.
* `edge()` is currently only enabled on resize, as the relative positioning and CSS transforms used to center thumbnails are suboptimal when coupled with frequent resizing.
* Next steps: For infinite scroll performance improvements, look into absolutely positioning attachment views and paging groups of attachment views.

`wp.media.view.UploaderWindow`
* Now generates a `$browser` element as the browse button (instead of a full `UploaderInline` view). Using a portable browse button prevents us from having to create a new `wp.Uploader` instance every time we want access to a browse button.

`wp.media.view.UploaderInline`
* No longer directly linked to the `UploaderWindow` view or its `wp.Uploader` instance.
* Used as the default `upload` state view.

`wp.media.view.Selection`
* An interactive representation of the selected `Attachments`.
* Based on the improved workflows, this is likely overkill. For simplicity's sake, will probably remove this in favor of `SelectionPreview`.

Media: Show an inline uploader when the media library is empty.

Merges most of `wp.media.controller.Upload` into `wp.media.controller.Library`, so we always create an inline uploader instead of an attachments browser if the state's `library` is empty.

props rzen, fixes #22323, see #21390.
