Unrolled build for #149839

Rollup merge of #149839 - theemathas:trivial-clone-pointee-sized, r=joboet

Use `PointeeSized` bound for `TrivialClone` impls

These `TrivialClone` impls previously had `?Sized` bounds, which are different from the `PointeeSized` bounds on the corresponding `Clone` and `Copy` impls. So, I've changed the `?Sized` bounds into `PointeeSized` bounds.

This mistake was made presumably because the `TrivialClone` PR (#135634) was opened in Jan 2025, but merged in Nov 2025. During that time, the sized hierachy PR (#137944) was opened in Mar 2025, and merged in Jun 2025. The `TrivialClone` PR was not updated to account for the sized hierachy changes.
