Series migration: Modify 'migrate' and 'migrate-incoming' QAPI commands for migration | expand

Commit Message

Het Gala July 10, 2023, 12:27 p.m. UTC 
migration_channels_and_uri_compatible() check for transport mechanism
suitable for multifd migration gets executed when the caller calls old
uri syntax. It needs it to be run when using the modern MigrateChannel
QAPI syntax too.

After URI -> 'MigrateChannel' object conversion,
migration_channels_and_uri_compatible() ->
migration_channels_and_transport_compatible() passes object as argument
and checks for valid transport mechanism.
