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:

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

Go support for Mobile devices

Go Reference

The Go mobile repository holds packages and build tools for using Go on mobile platforms.

Package documentation as a starting point:

Caution image

The Go Mobile project is experimental. Use this at your own risk. While we are working hard to improve it, neither Google nor the Go team can provide end-user support.

This is early work and installing the build system requires Go 1.5. Follow the instructions on golang.org/wiki/Mobile to install the gomobile command, build the basic and the bind example apps.
