Auto merge of #40409 - mbrubeck:calloc, r=sfackler
Specialize Vec::from_elem to use calloc Fixes #38723. This specializes the implementation for `u8` only, but it could be extended to other zeroable types if desired. I haven't tested this extensively, but I did verify that it gives the expected performance boost for large `vec![0; n]` allocations with both alloc_system and jemalloc, on Linux. (I have not tested or even built the Windows code.)
