[autotest] Rename site_host.SiteHost to cros_host.CrosHost

Rename site_host.SiteHost to cros_host.CrosHost.
cros_host.CrosHost is the new chromeos specific host class.
The concept 'SiteHost' is deprecated as we are dealing with
multiple types of hosts (e.g. ServoHost).
The concept of a single'SiteHost' doesn't meet our needs any more.

All references are updated.

SerialHost is now subclassing RemoteHost and mixes in CrosHost
in hosts.factory.create_host().

BUG=chromium:273833
TEST=Trybot build passes; Repair/Verify pass;
Dummy suite passes;
Server side test platform_InstallTestImage
which is affected by this CL passes.
DEPLOY=scheduler
