Relevant upstream PR: rust-lang/rust#137944 (Sized Hierarchy: Part I). This PR implements a part of RFC 3729, which prescribes a hierarchy of Sized traits. Notably, this disallows instantiation of size_of_val and align_of_val with extern types. Consequently, the code in tests unsized_foreign.rs as well as parts of foreign_type.rs no longer compile (when previously some of the tests would panic). These test were therefore removed.

Resolves: #4165

Relevant upstream PR: rust-lang/rust#137944
(Sized Hierarchy: Part I). This PR implements a part of
[RFC 3729](rust-lang/rfcs#3729), which
prescribes a hierarchy of `Sized` traits. Notably, this disallows
instantiation of `size_of_val` and `align_of_val` with extern types.
Consequently, the code in test `unsized_foreign.rs` no longer compiles
instead of panicking, as it previously did. This test is therefore
removed.

Work in progress: figure out whether we can make `foreign_type.rs` work.
