MOZ_SERVICES_SYNC should have been removed in Moz Bug 1227361.
However, it is still available, so we would like to use it.
Since it is a configuration that Mozilla does not test, and using it
results in a build error and in a few runtime errors, too.
This commit fixes them.

We have an upstream bug, too, but its (proposed) fix does not apply to
ESR 102 because of ESMification.
Should it not be accepted, we could replace this commit with the
poposed fix.

Bug 1769030: Add a configure flag to load policies only from the local policies.json file r=mkaply,glandium

Add a configuration flag to make Enterprise Policies mechanism only
consult a policies.json file (avoiding the Windows Registry, macOS's
file system attributes, and /etc/firefox/policies/policies.json on
other OS).

Bug 1757809 - Provide a JsonSchema module that supports additional Mozilla-specific formats r=mossop,emcminn

In migrating from Ajv 6 to @cfworker/json-schema, some schemas will no longer
validate due to the `format: uri` annotation only being a suggestion for
strings in Ajv 6. Our URLs that use %PLACEHOLDERS% (e.g., `%LOCALE%`) will not
pass validation as URIs due to being interpreted as invalid URL encoding.

Here we add a facade in front of @cfworker/json-schema which defines a
`moz-url-format` format for strings, which runs them through
Services.urlFormatter.formatURL before attempting to validate them as URIs. We
don't simply find-replace all %PLACEHOLDERS% because the URL formatter service
only supports certain variables and will leave undefined variables as-is,
leading to a validation error (which is what we want).

My immediate use case is making the name for a Windows Scheduled Tasks
agree with the existing task names for the Windows Default Browser
Agent task name.  The latter uses `MOZ_APP_DISPLAYNAME` in its static
metadata and from C++.

We want to strongly discourage users from using `MOZ_APP_DISPLAYNAME`
in dynamic contexts, hence the unusual name and long comment; but it's
not worth establishing a lint limiting uses at this time.
