Add objc strict includes to include paths

This is in prepareation for the ObjcProvider to CcCompilationContext
migration.  After the migration, a target must get its strict
dependency includes by inspecting the strict_include fields of its
objc dependencies.  This change is also compatible with pre-migration.
