Rollup merge of #138034 - thaliaarchi:use-prelude-size-of, r=tgross35

library: Use `size_of` from the prelude instead of imported

Use `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the prelude instead of importing or qualifying them.

These functions were added to all preludes in Rust 1.80.
