This commit un-deprecates DeprecatedString, and repurposes it as a byte string. As the null state has already been removed, there are no other particularly hairy blockers in repurposing this type as a byte string (what it _really_ is). This commit is auto-generated: $ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \ Meta Ports Ladybird Tests Kernel) $ perl -pie 's/\bDeprecatedString\b/ByteString/g; s/deprecated_string/byte_string/g' $xs $ clang-format --style=file -i \ $(git diff --name-only | grep \.cpp\|\.h) $ gn format $(git ls-files '*.gn' '*.gni')
