Add alexa check for "name" channelMetadata attribute (#29279)

* Added check for "name" channelMetada attribute

* Added/changed smart home media player tests for added value name in chanelMetadata payload section

* Since Alexa only expects a number/callSign/affiliate in the returned response, returning "name" is not technically valid.  Modified to return the value in the callSign field  instead since it's a text value. Since there is no returned channel number, cannot return a true numeric value in "channel" field
