Propagate third_party public_include_dirs to include_dirs

We previously moved them to only being added via -isystem
(and -imsvc). This prevents warnings in those headers from
breaking our builds, which is good.

However, when generating Visual Studio project files, GN
doesn't know about those switches, so it omits these paths.
Propagating to include_dirs causes them to be added, and
fixes include path and symbol resolution in the IDE.
