[DO NOT MERGE] Reject non-ASCII hostnames and SANs, Ignore DNS names in certificate CN.

Removes the possibility of certificates spoofing DNS names by
exploiting name collisions when lowercasing Unicode characters.
Note that the relevant RFCs mandate that domain names in
certificates should be stored using IDNA 2008 rules, i.e. as
ASCII punycode.

Ignoring DNS names in the certificate CN is a backport of a
change made in Android P as this behaviour has been deprecated
for many years.  The P change was not gated on targetSdkVersion,
so all apps on P or later ignore the CN field when verifiying
hostnames, this change bring O MR1 into line with best practices
without introducing significant fragmentation.  The change makes
hostname verification consistent across all releases with security
patch support.
