Werk #10186: Windows Agent executes 'wmi_cpuload' section separately

Previously the 'wmi_cpuload' section had been executed together with all other sections and plugins. This could result in realistic looking, but definitely too high numbers for the CPU load especially when the CPU is weak.

Now the Windows Agent launches the 'wmi_cpuload' section at the very beginning of the processing cycle, both alone and synchronous, thus providing precise results for the CPU-load.
