Make SchemaLoader independent of current working directory.

The SchemaLoader looks for schema files in the current directory. This
isn't very robust and may cause problems for other products than
Chromium if they run the script from a GYP file in another directory.

The SchemaLoader is supplied two arguments now: the path to API files
relative to the root path (for use in #includes) and the regular path
to API files (for file access).

Fixes use after free in NativeViewHost::SetPreferredSize

I believe what's happening here is Close() is getting invoked
subsequently followed by a RepositionToBalloon() that starts
an animation that is getting triggered before the Widget finishes
closing.
