Make basic chamelium function accessible to other tests

There are many use case where we can integrate chamelium with other tests,
Migrating some of basic chamelium functions to igt_chamelium lib to avoid
Code rewriting.

v2: Moved one more function reset_state from tests/kms_chamelium to
lib/igt_chamelium.

v3: - Shifted disabling of modeset to igt_kms
    - Replace connection_str with kmstest_connector_status_str (Petri)
    - Generalized require__connector_present (Petri)
    - Avoided using data_chamelium_t struct (Petri)

v4: - Moved function to library (Petri)
    - Renamed some functions and added documentation (Petri)

v6: - Documentation of functions(Petri)
    - Shifted function to igt_kms and renamed (Petri)
