Matthias Krüger e5a69bb215 Rollup merge of #148683 - fmease:rm-const_trait-attr, r=fee1-dead

Remove `#[const_trait]`

Remove `#[const_trait]` since we now have `const trait`. Update all structured diagnostics that still suggested the attribute.

r? ```@rust-lang/project-const-traits```

README.md

This directory contains the test for incorrect usage of specialization that should lead to compile failure. Those tests break down into a few categories:

Feature gating
- On use of the default keyword
- On overlapping impls
Overlap checking with specialization enabled
- Basic overlap scenarios
  - Includes purely structural overlap
  - Includes purely trait-based overlap
  - Includes mix
- Overlap with differing polarity
Attempt to specialize without using default
Attempt to change impl polarity in a specialization
Attempt to rely on projection of a default type
- Rely on it externally in both generic and monomorphic contexts
- Rely on it both within an impl and outside it
