windows: fix EnumProcesses to pass the correct array size

Implementation generated directly with mkwinsyscall has a wrong
assumption about the expected value for PIDs buffer size.

This change adds some small manual code that converts the input
slice length to the number of bytes of the array backing the slice.

A test is also added. It fails with the previous implementation.

Fixes golang/go#60223
