Separate agg-authored code from fx-authored code.chromium/2439chromium/2438chromium/2437chromium/2436chromium/2435

Creates a separate library so we can apply less-strict warnings to
the code we can't change from upstream vs. the code we can change,
reducing noise in the standalone build.

Remove needless foo.{cpp,h} files that merely perform indirection
via #include "some_other_path/foo.{cpp,h}".
