Fix Windows perfcounters for non-English systems

The `ValidatePath` syscall only operates in a localized language mode,
however `AddEnglishCounter` always works with English-localized counter
names. This means that on non-English systems, the counter will work but
will fail validation.

The only solution is to not validate the counter. There is no
corresponding `ValidateEnglishPath` syscall. `CollectQueryData` will
still error if the counter is invalid.
