`wrapping_rem` methods should document panic-on-zero

[yoshuawuyts]

Location

All wrapping_rem methods.

Summary

As reported in yoshuawuyts/futures-concurrency#156, when calling the wrapping_rem functions with a value of 0, a panic is triggered. The documentation of the wrapping_rem method should include a # panic section making note of this.

Example

playground

100usize.wrapping_rem(0);

thread 'main' panicked at 'attempt to calculate the remainder with a divisor of zero',

It seems that this is correctly documented for the signed integer types, but not the unsigned ones. So a quick copy-paste should be sufficient.
