Add media_cdm_adapter.gyp: a common base for all CDM adapters.

This removes duplicate code in CDM adapter gyp targets.

Also move more code under the condition enable_pepper_cdms==1 so that when enable_pepper_cdms==0, clearkeycdm, clearkeycdmadapter and widevinecdmadapter targets won't exist.

BUG=329097
TEST=Widevine and ClearKey CDM adapters still work.
