Move build/ to build_gyp/.

This CL moves the build/ files to build_gyp/ in anticipation of pulling in
Chromiums build/ directory.

The gyp_pdfium files have been duplicated into both places. Once the bots
are updated we'll remove the build/ versions.

File build/gyp_pdfium (right):

https://codereview.chromium.org/1900913003/diff/1/build/gyp_pdfium#newcode1
build/gyp_pdfium:1: #!/usr/bin/env python
Should this file have been deleted in favor of build_gyp/gyp_pdfium?

be removed.
