Port Windows QPA plugin to new logger API.

Introduce logging categories and change most debug statements
to qCDebug().

Retrieve the filter rules from the environment variable
QT_QPA_VERBOSE (should be removed once the logging framework
offers a more convenient way of configuring).

Replace the old per-category variables controlling verboseness
of the output by a single variable which can be set on the command
line.
