chromeos_config: Use an instance of HWTestList.

HWTestList contains a bunch of class methods for defining HWTests
values. This CL converts those into member variables, and creates an
instance of HWTestList which is passed to the methods which need it.

This has no meaningful effect, but a later change will set values on
the new HWTestList instance which will change the tests generated.

chromeos_config: Discover IS_RELEASE_CHANNEL.

IS_RELEASE_CHANNEL was a global variable in chromeos_config that had to
be manually updated whenever a new release branch was created. It will
now automatically discover the correct value based on data sent to use
from GE.
