Create separate target for policy_templates to fix current build problems
Create separate target for policy_templates to fix current build problems

This is for fixing the problem introduced in CL 3068012 that causes the target chrome_strings to be invoked each time Chrome is built.

BUG=None
TEST=Manual: build chrome, then build it again without making any modifications. Check that targets policy_templates and chrome_strings were not invoked.
