[3.13] gh-156115: Use the simulator deployment-target flag for iOS simulator builds (GH-156116) (#156213) Ensures that CFLAGS and LDFLAGS use -mios-simulator-version-min, rather than the device-based -mios-version-min. This only matters if the CFLAGS and LDFLAGS are used in a bare call to clang without a -target; but that is a legal usage, so it's worth catching.
