LibJS: Fix indexed access of TypedArray with byte offset

By doing the offset calculation in {get,put}_by_index() we would
delegate these operations to Object for any index >= (array length -
byte offset). By doing the offset calculation in data() instead, we can
just use the unaltered property index for indexing the returned Span.
In other words: data()[0] now returns the same value as indexing the
TypedArray at index 0 in JS.

This also fixes a bug in the js REPL which would not consider the byte
offset and subsequently access the underlying ArrayBuffer data with a
wrong index.
