Json writer, support larger signed integers upto 2^53
Previously only 32bit signed integers were ensured to be supported by
JsonValue type via API but it is expected that a larger integer range
should be supported by a JSON implementation.
This commit brings the Qt implementation into parity with NodeJS
JSON.stringify() in respect of the JavaScript Number type.
