Adding tests for MCOL-4531 New string-to-decimal conversion implementation
And also for: - MCOL-4462 CAST(varchar_expr AS DECIMAL(M,N)) returns a wrong result - MCOL-4500 Bit functions processing throws internally trying to cast char into decimal representation - MCOL-4532 CAST(AS DECIMAL) returns a garbage for large values (which were fixed by the same patch)
