Mark Pulford a5c44f3e3f math: add RoundToEven function 
Rounding ties to even is statistically useful for some applications.
This implementation completes IEEE float64 rounding mode support (in
addition to Round, Ceil, Floor, Trunc).

This function avoids subtle faults found in ad-hoc implementations, and
is simple enough to be inlined by the compiler.

Fixes #21748
