cmd/gomobile: improve support for macOS and Catalyst

This is is a follow-up from my previous PR (#65). It makes gomobile
aware of GOOS=ios and adds support for specifying specific Apple
platforms, instead of overloading the "ios" platform.

Supported platforms: ios, iossimulator, macos, and maccatalyst

These can now be specified the -target argument to gomobile, e.g.:
gomobile build -target=ios,iossimulator,macos,maccatalyst

It preserves the current behavior of -target=ios, which will build for
ios and iossimulator on supported architectures (arm64 and amd64).

It adds platform-specific build tags so Go code can discriminate between
different Apple platforms like maccatalyst (UIKit on macOS).

This PR also fixes a number of broken tests.

TODO: cgo has a bug where c-archive builds targeting Catalyst will fail
unless -tags=ios is supplied. See https://golang.org/issues/47228
