crypto/x509: document support for leading periods in DNS constraints

This change adds a comment to the Verify documentation that indicates
that you can use URI and email style name constraints with a leading
period for DNS names (and explains what they do). This behavior is
not standards compliant, but matches the community application of
RFC 5280, so it makes sense to document it.

Fixes #37535
