RFR: 8308306: Update to Xcode 14.3 on macOS [v2]

[Kevin Rushforth]

> Update the compiler on macOS to Xcode 14.3. In addition to providing the needed C++20 support for the next WebKit update, initial testing by the JDK team shows that this fixes a reproducible builds problem, so it might help address [JDK-8306886](https://bugs.openjdk.org/browse/JDK-8306886).
> 
> Xcode 14.3 requires macOS 13 Ventura to build (although it is known to build on macOS 12 Monterey, which might be useful for developer builds). The generated JavaFX code will run on older versions of macOS.
