Fix content_browsertests and other full stack tests in multiple_dll

Fix content_browsertests and other full stack tests in multiple_dll

Tests need both sets of entry point functions, ContentClient embedder
pointers, etc. Now in gyp, the three targets are content_app_browser for
browser-only, content_app_child, which is child-only, and
content_app_both which contains both.
