Remove preset filter configurations from Problems and Tasks views

Remove the predefined markerFieldConfiguration entries from plugin.xml
that populated the filter dialog with opaque preset entries like
'Errors/Warnings on Project', 'Warnings on Selection', 'All Errors
on Workspace', and 'TODOs'. These presets were all disabled by default
and added clutter to the filter configurations list without providing
clear value to users.

Also remove the now-unused parameter classes:
- ErrorsWarningsParameters
- SelectedWarningsParameters
- AllErrorsParameters
- TodoFiltersContributionParameters
