SentrySDK: Turn on deep integration on demand

Only whenever the sentry_sdk module is there functions of this module will be used.
The only changes, which were needed to be made, are done on cura_app.py and cura.CrashHandler.
Whenever the module is not available, it's functions will be omitted.

The if-clauses could happen earlier, but this at least the bare minimum, and, to be honest, on Ultimaker's distribution it won't speed up anything.
I expect the if-clause to take the same amount of runtime sooner or later. The check is the same and it should be on Ultimaker's distribution always be "True".
