process-level metrics for win_stat input plugin

[gracewehner]

Is your feature request related to a problem? Please describe.
The proc and cpu input plugins for linux allow a process name/pid to be specified to be able to get memory and cpu usage stats. There is no equivalent to this for windows.

Describe the solution you'd like
Allow a parameter to specify a process for the win_stat plugin to get cpu and memory stats for the specific process.

Additional context
We are using proc and cpu input plugins to monitor usage for specific processes for linux but would like an equivalent for our windows workloads.

we have a native metrics collector that supports CPU samples:

Thanks @edsiper. Unfortunately, we can only currently use the logs pipeline, as this is what our custom output plugin supports.
