Taylor Cramer d00d4dfe0d Refactor dyn-compatibility error and suggestions
This CL makes a number of small changes to dyn compatibility errors:
- "object safety" has been renamed to "dyn-compatibility" throughout
- "Convert to enum" suggestions are no longer generated when there
  exists a type-generic impl of the trait or an impl for `dyn OtherTrait`
- Several error messages are reorganized for user readability

Additionally, the dyn compatibility error creation code has been
split out into functions.

error[E0038]: the trait `AsyncFnMut` is not dyn compatible
--> $DIR/dyn-pos.rs:3:16
|
LL | fn foo(x: &dyn AsyncFn()) {}
| ^^^^^^^^^ `AsyncFnMut` is not dyn compatible
|
note: for a trait to be dyn compatible it needs to allow building a vtable

--> $SRC_DIR/core/src/ops/async_function.rs:LL:COL

= note: the trait is not dyn compatible because it contains the generic associated type `CallRefFuture`
