Do MpdBuilder test TODOs 

- Added factory methods for creating Representation and AdaptationSet in
  tests.
- Since most tests only needed access to the constructors for
  Representation and AdaptationSet, instead of using
  FRIEND_TEST_ALL_PREFIXES() for each test case, added factory methods
  on the test class.
- Check the 'frameRate' attribute in
  CommonMpbBuilderTest.SetSampleDuration.
