As suggested in GH-12286. This results in slightly better assembly in clang,
because the expected case will be handled by a forwar

It fixes round

Reimplement `php_round_helper()` using `modf()` (#12220)

This change makes the implementation much easier to understand, by explicitly
handling the various cases.

It fixes rounding for `0.49999999999999994`, because no loss of precision
happens by adding / subtracing `0.5` before turning the result into an integral
float. Instead the fractional parts are explicitly compared.

see GH-12143 (this fixes one of the reported cases)
Closes GH-12159 which was an alternative attempt to fix the rounding issue for
`0.49999999999999994`
