tdf#96821 fix corner cases for Calc function ROUND.

For very large integer numbers, e.g. 2^52+1, ROUND produced incorrect
results because rtl::math::round uses
floor( number + 0.5 + small_correction_value ), which reduces the maximum
possible mantissa resolution.a

Correction of several unit test documents (Calc functions) with rounding
errors that only became apparent with this fix.
