Add export_*_lib_headers to static and shared properties

Allow specifying export_static_lib_headers and export_shared_lib_headers
in the static or shared properties of cc_library modules.

Use a named struct for the properties to avoid having to create
a runtime struct type since none of the properties are filtered.
This avoids running into the name length limit in runtime.StructOf.
