x.py: do not build Miri by default on stable/beta

Fixes https://github.com/rust-lang/rust/issues/73117

Do I need to do anything to make sure Miri is still built by the tools CI builder? Are there other tools that should be off-by-default?

Also, unfortunately the `DEFAULT` associated const has no doc comment, so I have no idea what it does, or why there are semmingly two places where the default build of tools is controlled.
