bors e2dc1a1c0f Auto merge of #129970 - lukas-code:LayoutCalculator, r=compiler-errors 
layout computation: gracefully handle unsized types in unexpected locations

This PR reworks the layout computation to eagerly return an error when encountering an unsized field where a sized field was expected, rather than delaying a bug and attempting to recover a layout. This is required, because with trivially false where clauses like `[T]: Sized`, any field can possible be an unsized type, without causing a compile error.

Since this PR removes the `delayed_bug` method from the `LayoutCalculator` trait, it essentially becomes the same as the `HasDataLayout` trait, so I've also refactored the `LayoutCalculator` to be a simple wrapper struct around a type that implements `HasDataLayout`.

The majority of the diff is whitespace changes, so viewing with whitespace ignored is advised.
