cli/command/image/build: deprecate ResolveAndValidateContextPath util

This utility was used internally and will be removed in the next release.
Use `DetectContextType` to detect the context-type, and use `GetContextFromLocalDir`,
`GetContextFromLocalDir`, `GetContextFromGitURL`, or `GetContextFromURL`
instead.
