This change ports all `EmbedderMsg` reply channels that don't use the `ROUTER` to GenericChannel. The remaining reply channels that use the router are blocked until #38973 is merged. This is a breaking change in the API between libservo and embedders. Future work: A lot of the reply channels in this PR look like they conceptually should be oneshot ipc channels. It might make sense to provide a `OneshotGenericChannel` abstraction that encodes this. Testing: No functional changes - covered by existing tests. None of the channels changed here uses the Router Part of #38912 --------- Signed-off-by: Jonathan Schwender <schwenderjonathan@gmail.com>
