Create a mock console to increase test coverage on mac

[TerryHowe]

What is the version of your ORAS CLI

1.2.0

What would you like to be added?

Increase test coverage on mac with mock console

Why is this needed for ORAS?

These tests do not run on mac because of X-code issue:

 % grep -r solaris cmd internal 
cmd/oras/internal/option/common_unix_test.go://go:build freebsd || linux || netbsd || openbsd || solaris
cmd/oras/internal/display/status/track/target_test.go://go:build freebsd || linux || netbsd || openbsd || solaris

1) Where should be mac test be run? 2) How to merge the test coverage of mac with linux's? 3) What SDK should be used to mock the console test on mac?

[TerryHowe]

1. I'm hoping that everything outside of cmd/oras/internal/display/status/progress would be tested on mac
2. I was hoping that a layer would be created at progress package that could be mocked with dependency injection
3. I was not planning on bringing in a package for mock, just go code.
