(Firefox :: Installer, enhancement, P3)

Description

Follow up to https://bugzilla.mozilla.org/show_bug.cgi?id=1736742.

com4:InProcessHandler seems to be the manifest entry we wanted at the time. We should be able to use it in place of the current runtime registration of Accessiblehandler.

Replaces runtime registration of AccessibleHandler for MSIX installs.

No users remain for this functionality. Knowing the registry isn't modified at runtime is useful in case we ever add devirtualization permissions for MSIX packages.

Backed out changeset d842a82ae3eb

Depends on D163554

Cache the World is enabled by default in Firefox 113, so we no longer need this. Bug 1821963 will include removal of MSIX registration of AccessibleHandler.
