Various changes in handling of profile compatiblilities

and the "show incompatible profiles" option.

It was not able to select the incompatible Print profile, which is
possible now.
(see Cannot select incompatible printer profile #3715)

When the Printer profile derived from the Prusa3D system profile was
active or a system Prusa3D profile was active, and when the Print profile
with the removed "inherits" field was active (or any other profile
derived from the "-- default --" profile was active), then the filament
selector offered just the profiles with the removed "inherits" field
(or any other profile derived from the "-- default--") profile.
This behavior has been now changed, so that in this scenario the Filament selector
will offer the Prusa3D vendor profiles compatible with the active Print
and Printer profile as well as the user profiles.

Slicer was also changed to keep an incompatible preset selected
at its respective tab if its respective "Red flag" is enabled.
For example, if an incompatible Print preset is selected and a Printer
profile is switched to another one which is not compatible with the active
Print preset that was red already, the active Print preset is
not switched if the Print "Red flag" is active. However, if the Print profile
was compatible before the Printer profile is switched and now the Print
profile becomes incompatible, another compatible Print profile is selected.

A likely bug in wxWidgets was worked around when switching a Print preset
on Plater, if the last item in the Print preset was active and incompatible,
and another Print preset was selected by the user. On Windows, an CBN_EDITCHANGE
is sent just after combo box selection change event and the CBN_EDITCHANGE
holds an index of the combo box item, which will be removed by the 1st event,
therefore leading to an assert in wxWidgets on CBN_EDITCHANGE. The workaround
is to disable processing of CBN_EDITCHANGE on Windows for the Plater
preset selection combo boxes.
