Refactor the deprecate_disable reason logic to a separate module.

This allows code to be used to show deprecation and disable information in brew info.

I will almost always run brew info before installing something, so it would be helpful to see whether the formula I'm about to install is deprecated or disabled.

Before:

$ brew info tj
tj: stable 7.0.0 (bottled)
Line timestamping tool
https://github.com/sgreben/tj
Not installed
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/tj.rb
==> Dependencies
Build: go ✘
==> Analytics
install: 0 (30 days), 1 (90 days), 21 (365 days)
install-on-request: 0 (30 days), 1 (90 days), 21 (365 days)
build-error: 0 (30 days)

After:

$ brew info tj
tj: stable 7.0.0 (bottled)
Line timestamping tool
https://github.com/sgreben/tj
Disabled because it has no license!
