mv_machine_learning: drop input and output type dependency from landmark detection

[Issue type] : code refactoring

Drop input and output type dependency from landmark detection task group
by making the input and output types specific to the landmark detection
task group to be inherited from the common types,
and then by making adapter class of the landmark detection task group
to use the common type instead of specific one.
