tests: dashdemux: add unit tests for checking the parsing of MPD element

Browse source 
Create a dash test target and add unit tests that check the parsing of
attributes of the MPD element and the following child elements:
 - baseURL
 - program information
 - location
 - metrics

These tests check the compliance of parts of the MPD parser in the
dashdemux element against the DASH specification [1].
