Noah Lev e0bd01167e Re-enable ConstArgKind::Path lowering by default

...and remove the `const_arg_path` feature gate as a result. It was only
a stopgap measure to fix the regression that the new lowering introduced
(which should now be fixed by this PR).

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
