Update the other example config files to work after restructuring encoder parameters

This is similar to what was done to welsenc.cfg in
3ba6a5f4daa.
Use TemporalLayerNum instead of GOPSize in other encoder config files

This is similar to what was done to welsenc.cfg in f5cd56ea74.
Set missed fields in ParamBaseTranscode

Previously, these fields kept whatever value was set by
FillDefault. The corresponding fields were set properly within
sSpatialLayers, but the fields within the main struct were left
with the default values.

This doesn't change the hashes in the unit test, since these
fields don't seem to be used in the produced bitstream at all.
Respect the loop filter disabling encoder parameter

Previously the loop filter was unconditionally enabled
regardless of what encoder parameter was set. If using
SEncParamBase instead, the loop filter was always disabled.
Respect the iDLayerQp parameter in SEncParamExt

Previously the value set in the parameter struct was ignored
completely.
Handle a -trace parameter for setting the trace level

A similar parameter already exists in the other version of
the ParseCommandLine function.

The WelsStderrSetTraceLevel isn't one of the functions that
is exported from wels.dll (nor welsenc.dll) though, so this
doesn't work (not currently either since the function is
currently already referenced) if we would try to link to the
encoder library dynamically.
