libs: encoder: set entrypoint based on tune automatically

Browse source 
Some profile, such as H265_MAIN_444 on new Intel platform, may only
support ENTRYPOINT_SLICE_ENCODE_LP entrypoint. This leads two
problems:

1. We need to specify the tune mode like `vaapih265enc tune=low-power`
   every time when we need to use this kind of profile. Or we can not
   create the encoder context successfully.

2. More seriously, we set the entrypoint to a fixed value in
   init_context_info() and so the create_test_context_config() can not
   create the test context for these profile and can not get the
   supported video formats, either.

We now change the entrypoint setting based on the tune option of the
encoder. If no tune property provided, we just choose the first
available entrypoint.
