1538348 - [meta] Implement the |downloads| extension API

Status: NEW

(GeckoView :: Extensions, enhancement, P3)

Description

[[ex-Mozilla] Agi Sferro | :agi]

The browser.downloads API is broken right now in GeckoView because it tries to request some android permissions using the Fennec-only (I'm assuming) DownloadCore.jsm.

In particular it uses shouldBlockForRuntimePermission: https://searchfox.org/mozilla-central/rev/7c20ad925005fbad7b8e08813115f1ec7fa1c248/toolkit/components/downloads/DownloadCore.jsm#421

We should just delegate this to the app. This is important because I think it's the only way that we have to save files from a web extension.

We will need this functionality for extensions that create files like screenshots.

Mass moving bugs to the Extension component.

GeckoView has implemented some parts of the downloads API, but it isn't actually hooked up with Android-Components (and by extension not available in Fenix). This is a feature request for the functionality: https://github.com/mozilla-mobile/fenix/issues/16585

Tentatively set this bug's priority to P2 so we review it for GV's 2022 H2 planning.
