8311546: Certificate name constraints improperly validated with leading period

[TheMangovnik]

Backport of JDK-8347424, JDK-8320372 and JDK-8311546.

Backporting this as it is marked as critical for the next CPU.

Tests

Tests were run on Fedora 44.

• test/jdk/sun/security/x509/DNSName/LeadingPeriod.java - PASSING
  • This test is introduced in this backport. Fails before the backport changes and passes after the change.
• test/jdk/sun/security - PASSING
  • Only sun/security/ssl/X509KeyManager/PreferredKey.java is failing, but that is unrelated to this backport.
• Tier 1 - PASSING
• gtest - PASSING
