cmd/gomobile: support macOS and Catalyst
Add support for macOS (non-Catalyst) and Catalyst targets. The compiled library is packaged into a "fat" XCFramework file (as opposed to a Framework), which includes binaries for iOS, macOS, MacCatalyst (iOS on macOS), and iOS Simulator targets, for amd64 and arm64 architectures. The generated XCFramework file is suitable for distribution as a binary Swift Package Manager package: https://developer.apple.com/documentation/swift_packages/distributing_binary_frameworks_as_swift_packages This change is based on earlier work: https://github.com/golang/mobile/pull/45 https://github.com/golang/mobile/pull/63 Fixes golang/go#36856 Change-Id: Iabe535183c7215c68838d6c8f31618d8bceefdcf GitHub-Last-Rev: 623f8f38653c856d2cd07e721f0932e515b50d02 GitHub-Pull-Request: golang/mobile#65 Reviewed-on: https://go-review.googlesource.com/c/mobile/+/310949 Reviewed-by: Hyang-Ah Hana Kim <hyangah@gmail.com> Reviewed-by: Hajime Hoshi <hajimehoshi@gmail.com> Trust: Hyang-Ah Hana Kim <hyangah@gmail.com> Trust: Hajime Hoshi <hajimehoshi@gmail.com> Run-TryBot: Hyang-Ah Hana Kim <hyangah@gmail.com> TryBot-Result: Go Bot <gobot@golang.org>
