Populate ChromeOS hardware_class in metrics log

Populate ChromeOS's hardware class in MetricsLog.RecordCoreSystemProfile
by implementing ChromeOS version of the HardwareModelName so that the
hardware_class field can be filled even for logs from previous run.
This is to fix large amount of ChromeOS reports have no hardware_class
problem.

This cl doesn't implement anything new but moves part of the
GetShortHardwareClass to ChromeOS's base::SysInfo::HardwareModelName().
This cl also does some cleanup in chromeos_metrics_provider and
removes GetShortHardwareClass function in variations_field_trial_creator.
The features::kUmaShortHWClass is always set to true now so some
conditions are no longer needed. The GetShortHardwareClass function is
replaced by base::SysInfo::HardwareModelName().

This cl will also affect our cloned install detection logic because
ChromeOS machine id can also be detected. Though, we'll not reset
client_ids because previously we never ran that logic.
