Bug 40091: Load HTTPS Everywhere as a builtin addon in desktop
This loads HTTPS Everywhere as a builtin addon from a hardcoded
resource:// URI in desktop. It also ensures that the non-builtin
HTTPS Everywhere addon is always uninstalled on browser startup.
The reason of making this desktop-only is that there are some issues
when installing a builtin extension from geckoview side, making
the extension not available on first startup. So, at least for
now we handle the Fenix case separately. See #40118 for a followup
for investigating these.
