Rename FromZeroes to FromZeros (#430)

Although both spellings are acceptable, "zeros" is the somewhat more
common [1] spelling of the plural noun "zero". We continue to use
the spelling "zeroes" for the verb; i.e., to replace bytes with the
value `0`. For user convenience, `FromZeroes` is retained as a
deprecated, `doc(hidden)` re-export of `FromZeros`.

Closes #431

 Zerocopy provides four core marker traits, each of which can be derived
