[Python] Make Logging Filtering global (#31944)

Log filtering is a global affair, so move the filtering functions to a
global context too. This allows to setup logging before creating any
device controller. It aligns with how the SDK treats logging.

Also enable log filtering for the Linux platform to make the
functionality useful on Linux.
