P3477 Obsoletes some wording in [bit.endian]

[eisenwave]

If all scalar types have size 1 byte, then all of endian​::​little, endian​::​big, and endian​::​native have the same value.

If there are 8 bits in a byte, then this obviously cannot happen. The proposal should contain wording changes which remove this.
