We're still getting a non-trivial number of issues from configurations
we don't support and don't plan to.
Let people know that we know their experience will not be good and what
to expect if they file issues.

This came up in https://github.com/Homebrew/homebrew-bundle/issues/1108
wherein a user had unwittingly untapped some official taps that get
automatically tapped on first use and couldn't figure out why they
couldn't use the associated command.
There's a few bits of functionality that Homebrew has changed over the
years, makes sense as a sensible default but some people find really
annoying:
- automatically running `brew update`
- automatically running `brew cleanup`
- automatically upgrading outdated dependents
- automatically reinstalling broken dependents
For each of these: let's improve the documentation of the commands
whose behaviour is changed and the environment variables themselves.
- Output `brew doctor` and `brew install` messages noting this configuration is (currently) unsupported and encourage use of Rosetta instead
- Output Rosetta 2 usage in `brew config` on ARM (whether in Rosetta 2 or not)
- Check the architecture of (newly installed) dependencies and ensure they are using the correct architecture.
- Don't allow installing macOS Intel Homebrew in macOS ARM Homebrew default prefix (and vice versa
- Actually write out the architecture of dependencies to the tab rather than generating and throwing them away
- Set and document the expected default prefix for macOS Intel Homebrew, macOS ARM Homebrew (`/opt/homebrew`) and Homebrew on Linux
While we're here:
- Don't say Big Sur is a prerelease version but still make it clear we
don't support it (yet).
- Don't reference non-existent IRC channel
Previously, running e.g. `brew help bundle` when homebrew-bundle was not
tapped would tap homebrew-bundle and then run `brew bundle` showing
`Error: No Brewfile found` instead of the expected help text.
Align the logic in `cleanup_portable_ruby` with that in `ruby.sh`.
