std: convert first_non_utf8_byte to use the iterator.
This makes it very slightly faster, especially when the string is valid
UTF-8, and completely removes the use of `unsafe` from the first half.
Before:
from_utf8_lossy_100_ascii ... bench: 151 ns/iter (+/- 17)
from_utf8_lossy_100_invalid ... bench: 447 ns/iter (+/- 33)
from_utf8_lossy_100_multibyte ... bench: 135 ns/iter (+/- 4)
from_utf8_lossy_invalid ... bench: 124 ns/iter (+/- 10
After:
from_utf8_lossy_100_ascii ... bench: 119 ns/iter (+/- 8)
from_utf8_lossy_100_invalid ... bench: 454 ns/iter (+/- 16)
from_utf8_lossy_100_multibyte ... bench: 116 ns/iter (+/- 9)
from_utf8_lossy_invalid ... bench: 119 ns/iter (+/- 9)
