fix: Suppress and log known exceptions during native initialization

[bitsandfoxes]

The SDK will no longer attempt to reinstall the backend without native support enabled and without successful initialization.
It'll also capture EntryPointNotFoundException during reinstallation.

We could have had this in here all along? :)
I dont' recall why we left on SentryInitialization originally, do you recall?

[bitsandfoxes]

The intention was to have everything annotated RuntimeInitializeOnLoadMethod in the SentryInitialization.cs so users could overwrite/remove it. But it should have belonged in SentryNative all along.

I actually though the flag was "UseNativeBackend" which we'll flip to false if native support was disabled, but also, on the catch block for the MissingEntryPoint.

And we can check that flag before doing any native calls. Or we don't need this because no native call is done anyway because we don't add the scope observers?

So the only thing left is making sure the BeforeScene thing doesn't run, hence the boolean you used in this PR? If that's the case there's no need to write LogDebug( "something failed") because nothing failed, just no backend was selected.

And no need for flipping any flag on the catch block either if no where else after this we'll need to know if it worked or not. (We could disable sessions if we're afraid of reporting 100% crash free rate, so the user will at least see a drop in sessions if it's a widespread error)?

Exactly, if the init failed we don't add the observers and we won't reinstall the backend.

Yes. Fair point. Updated the logs! Thanks!
