[jdk8u-dev] RFR: 8321489: Update LCMS to 2.16

Fri Aug 22 16:55:27 UTC 2025

I'd like to backport it for parity with Oracle 8u.
11u patch applies almost cleanly, except for a license update in THIRD_PARTY_README instead of lcms.md.

GHA testing passes without regressions, test failures look unrelated. Additionally tested manually with J2Ddemo.
