Upgrades to Glean v50.0.1, which comes with a rewritten core and UniFFI-powered bindings. Glean has some API changes, so we swap it over to that. Mostly mechanical changes. Also upgrades to inherent v1.0 in fog. This matches what Glean uses internally and gets rid of one duplicated crate. Also upgrades to glean-parser==6.0.1 One crate duplication now (change in `python/mozbuild/mozbuild/vendor/vendor_rust.py` required). Some new crates now vendored. These are transitive dependencies of Glean dependencies, all with valid licenses and already used in other products (mobile). Differential Revision: https://phabricator.services.mozilla.com/D146062
