Don't rebuild raw strings when unescaping.

Raw strings don't have escape sequences, so for them "unescaping" just
means checking for invalid chars like bare CR. Which means there is no
need to rebuild them one char or byte at a time while escaping, because
the unescaped version will be the same. This commit removes that
rebuilding.

Also, the commit changes things so that "unescaping" is unconditional for
raw strings and raw byte strings. That's simpler and they're rare enough
that the perf effect is negligible.
