Replace `#[default_method_body_is_const]` with `#[const_trait]`

pulled out of #96077

related issues:  #67792 and #92158

cc `@fee1-dead`

This is groundwork to only allowing `impl const Trait` for traits that are marked with `#[const_trait]`. This is necessary to prevent adding a new default method from becoming a breaking change (as it could be a non-const fn).
