fix: Devmode unused function warnings on new MSVC (#1342)

MSVC apparently has overrides for the two definitions of operator== in
unittest/test_util_string.cpp in the <utility> header, raising a warning
about them being local unused functions:

https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-4-c4505?view=msvc-170

Disable this warning type in cmake/DevModeWarnings.cmake for MSVC.
