Auto merge of #14336 - swarnimarun:remove-slice, r=lnicola

internal: add `as_slice` to `hir::Type`

~`remove_slice`~ `as_slice` is same as `remove_ref` but for slices.

Though there is `as_array` which I believe was named such because it also gets the length of the array, maybe. I am still shaky on the names feel free to suggest corrections.
