[igt-dev] [PATCH i-g-t v2 1/3] 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.
