Do all Android and iOS devices support this feature?

iOS since 11.0 (2017, >98% of iOS users today): https://en.wikipedia.org/wiki/IOS_11#Other_changes
I don't know what version it was introduced, but this has been around for quite a while and doesn't rely on proprietary google services or anything, so I expect all phones have it (though maybe your QR code reader needs to support the format).
