1911833 - Implement initial MV3 userScripts API bindings

Status: NEW

(WebExtensions :: General, enhancement, P1)

Description

[Rob Wu [:robwu]]

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

In-scope:

• userScripts.register, userScripts.unregister, userScripts.getScripts()
• MAIN world only.
• with persistency. Depends on skv (bug 1909409), but if that is not ready yet we can land with rkv at first and before enabling userScripts by default, switch to skv.

Attachment: Bug 1911833 - Add MV3 userScripts namespace, separate from MV2

• Add "userScripts" permission for MV3.

• Add "userScripts" namespace for MV3, and add schema and logic to make
  sure that this namespace is limited to MV3 only.

• Add tests to verify that the "userScripts" namespace of MV2 and MV3
  are completely isolated.

• The functionality in this patch is limited to verifying that the API
  bindings and permission requirement works; the rest of the
  implementation will follow in the next patches.
