PDBFileBuilder supports two different ways to create files. One is PDBFileBuilder::commit. That function takes a filename and write a result to the file. The other is PDBFileBuilder::build. That returns a new PDBFile object. This patch removes the latter because no one is using it and in a real life situation we are very unlikely to need it. Even if you need it, it'd be easy to write a new PDB to a memory buffer and read it back. Removing PDBFileBuilder::build enables us to remove other classes build transitively.
