runtime: revert "do not call timeBeginPeriod on windows"
This reverts commit
ab4c9298b8185a056ff1152f2c7bd9b38d3d06f3.
Sysmon critically depends on system timer resolution for retaking
of Ps blocked in system calls. See #14790 for an example
of a program where execution time goes from 2ms to 30ms if
timeBeginPeriod(1) is not used.
We can remove timeBeginPeriod(1) when we support UMS (#7876).
Update #14790
