Implement NPNVsupportsCompositingCoreAnimationPluginsBool

Returns true when plugin compositing is enabled, so that plugins that dynamically query for composited CA support know it's safe to use CA.

Updates NPAPI headers to r14 of the upstream 'npapi-sdk' project headers, to pick up the new constant.

BUG=40997
TEST=HTML overlays should work with, e.g., the Google Earth plugin on 10.6+
