UI: Introduce View pie in more editors

#### Motivation

The View pie menu is a convenient way to access operators such as `Frame Selected` and `Frame All` which are usually mapped to `PERIOD` or `HOME` keys on the right side of most keyboard, making it hard hard to reach with the left hand.

The motivation for this patch comes from working with a 75% keyboard (no numpad). Most laptops face a similar problem.

#### Implementation

The View pie menu has been added to the following editors and sub-modes where applicable:

* Node Editor
* Video Sequencer
* Dopesheet
* Graph
* NLA
* Image
* Clip
* Outliner

More options could definitely be added to this menu for convenience, as long as it maintains the common options in the same place (Frame Selected on the left, Frame All on the right).

For positioning I went with the following layout:
{F11791186, size=full}

I've added `Zoom 1:1`to the Image Editor and the VSE Preview since there is no way to reset the zoom on keyboards without numpad (unless Emulate Numpad is turned on).

The Outliner uses `Show Active` and `Show Hierarchy` which are the closest ones to the equivalent in other editors. Should `Show Active` be renamed to `Frame Selected`?

The shortcut assigned is the same as the 3D Viewport (`ACCENT_GRAVE`).
