[api-minor] Remove all the useless telemetry stuff in the viewer (bug 1802468)

Browse source 
Add a deprecation notification for PDFDocumentLoadingTask.onUnsupportedFeature and PDFDocumentProxy.stats
which are likely useless.
The unsupported feature stuff have initially been added in (#4048) in order to be able to display a
warning bar and to help to have some numbers to know how a feature was used.
Those data are no more used in Firefox.
