RFR: JDK-8279397: Update --release 18 symbol information for JDK 18 build 32

[Joe Darcy]

Update of JDK 18 symbol information for build 32.

@lahodaj , can you take a look at the diff? Given the code changes for JDK-8270416: "Enhance construction of Identity maps" (https://github.com/openjdk/jdk/commit/5832a3440489d0967dc3b0542c1ace51eed292d6), I didn't see why the symbol update was triggered.
