Implement BigInt primitve type and some of its operations (#4062)

Supported operations: - parse BigInt (decimal, hexadecimal, binary) - toString with any radix between 2 and 36 - arithmetic operations: negate, add, subtract, multiply, divide, modulo - left and right shift JerryScript-DCO-1.0-Signed-off-by: Zoltan Herczeg zherczeg.u-szeged@partner.samsung.com
