Flip document and parser ownership
This Cl switches the ownership between the parser and the document. Previously the parser owned the document and we'd jump through hoops during cleanup to delete the right object. This Cl flips the ownership so the document owns the parser and simplifies the cleanup logic where needed. BUG=pdfium:565 Review-Url: https://codereview.chromium.org/2275773003
