1911835 - Implement USER_SCRIPT world

Status: RESOLVED FIXED

(WebExtensions :: General, enhancement, P2)

Description

[Rob Wu [:robwu]]

See https://bugzilla.mozilla.org/show_bug.cgi?id=1875475#c3 for details.

User scripts should be able to execute in its own world. There is a default USER_SCRIPT world, but an extension can also specify a different world by worldId (https://github.com/w3c/webextensions/blob/main/proposals/multiple_user_script_worlds.md).

A world that the user script executes in is essentially its own sandbox. The default CSP of that world is configurable, per worldId.

This patch adds the USER_SCRIPT value as a supported value in the
internal WebExtensionContentScript constructor.

This patch does not introduce a distinct USER_SCRIPT sandbox yet; that
will be done in the next patch.
