[FEAT] add flag with null value

I intend to configure the provisioning profile to contain a specific value for iOS, but a null value for macOS. (I don’t have the license for macOS). Adding a flag with an empty value is not possible today. It is not possible for me to define the indicator as follows:

"PROVISIONING_PROFILE_SPECIFIER[sdk=macosx*]" = ""

This would avoid having the same value for PROVISIONING_PROFILE_SPECIFIER[sdk=macosx*] and PROVISIONING_PROFILE_SPECIFIER[sdk=macosx*] in my XCode project settings.
