feat(tvix/store): improve error message formatting

Browse source 
WrongSorting(Vec<u8>) actually encodes the name of a node, so if we can,
we want this to display it as a string (and fall back to the base64
encoding if we can't).

Before:

> rpc error: code = InvalidArgument desc = directory b3:yfwNlpPm8MkrRvshGHfgMtKLoSDtX2pKliVuVWmUt5g= failed validation: [108, 111, 99, 97, 108, 101] is not sorted

After:

> rpc error: code = InvalidArgument desc = directory b3:yfwNlpPm8MkrRvshGHfgMtKLoSDtX2pKliVuVWmUt5g= failed validation: locale is not sorted
