Temporary fix to support building pytorch from fbsource (for xplat dependencies) (#31393)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/31393
pytorch build was set up with the include paths (-I) relative to fbcode/. This works well for fbcode builds, but doesn't work for the new fbcode_deps args for xplat build targets that work across xplat and fbcode. When these targets are built, the include paths need to be relative to fbsource, so fbcode/ suffix needs to be added to those paths.
Longer term, to properly fix this, we need to use raw_headers with public_include_directories specified for all of these targets.
