Add feature flag to change the CDM version to 18.0.2

[ Merge of http://go/wvgerrit/191139 ]

Adding an initial flag that include identifiable differences when
the feature is enabled or disabled.

This is the same commit as ag/25837302. It was reverted due to
memory size issues. A follow on CL will address that issue to
ease review.
