Move the CDM version string to a header file

[ Merge of http://go/wvgerrit/95943 ]

The CDM version for android is now defined in a platform specific
header file. A check for version number match has been removed
from integration tests as it will always be true. We will still
get a notification to change the CDM version when the Android OS
version gets updated.
