Strengthen soundness proof for size_of_val_raw #1574

  1. Strengthen soundness proof for size_of_val_raw 

    Previously, we needed to rely on the fact that the instance of any valid
Rust type with 0 elements has a size (in number of bytes) which is not
greater than `isize::MAX`. Providing this as a guarantee turned out to
be controversial. [1]

This was made possible by rust-lang/rust#126152.
