Changes to adapter + gyp to support v15

Bug: b/117558570
Test: Android, CE CDM, and Linux tests
Merge of http://go/wvgerrit/67566

This CL adds changes to support the Level 3 upgrade to v15 with both the
dynamic and static adapters. It also rearranges the wvcrc.cpp files so
that the tests have their own copy and Level 3 can just use the one in
ref/src.
