Import pw_build_defaults into child GN targets

This moves the pw_build_default imports in pw_* target types from the
enclosing tempalate's scope into the generated target's. This allows
downstream projects to check the existence of the pw_build_defaults
variable to determine whether they're building a pw_* target or the GN
builtin.
