RFR: 8315870: icu fails to compile with Visual Studio 2022 17.6.5

Thu Sep 7 22:01:58 UTC 2023

Fix icu to compile with the latest VS 2022 compilers. Note that this fix is already present in the upstream ICU repo. See unicode-org/icu at c7e967c456ceff6436607ca2a3da034320ca34c3

I've built this using the current compilers on all three platforms, and on Windows using VS 2022 17.6.5.
