Unify the common code of `Utf8Value`, `TwoByteValue`, `BufferValue`
and `StringBytes::InlineDecoder` into one class. Always make the
result zero-terminated for the first three.
This fixes two problems in passing:
* When the conversion of the input value to String fails,
make the buffer zero-terminated anyway. Previously, this would
have resulted in possibly reading uninitialized data in multiple
places in the code. An instance of that problem can be reproduced
by running e.g.
`valgrind node -e 'net.isIP({ toString() { throw Error() } })'`.
* Previously, `BufferValue` copied one byte too much from the source,
possibly resulting in an out-of-bounds memory access.
This can be reproduced by running e.g.
`valgrind node -e \
'fs.openSync(Buffer.from("node".repeat(8192)), "r")'`.
Further minor changes:
* This lifts the `out()` method of `StringBytes::InlineDecoder`
to the common class so that it can be used when using the
overloaded `operator*` does not seem appropiate.
* Hopefully clearer variable names.
* Add checks to make sure the length of the data does not exceed
the allocated storage size, including the possible null terminator.
