SmokeTester should use `SentrySdk.CrashedLastRun`

[bitsandfoxes]

Description

The SmokeTester uses the workaround going through the options to get to the CrashedLastRun

sentry-unity/test/Scripts.Integration.Test/Scripts/OptionsConfiguration.cs

Lines 31 to 38 in fcd5e99

	SmokeTester.CrashedLastRun = () =>
	{
	if (options.CrashedLastRun != null)
	{
	return options.CrashedLastRun() ? 1 : 0;
	}
	return -2;
	};

It should use the public SentrySdk.CrashedLastRun instead

sentry-unity/src/Sentry.Unity/SentryUnitySdk.cs

Line 95 in fcd5e99

public SentrySdk.CrashedLastRun CrashedLastRun()

[linear]

UNITY-151 SmokeTester should use `SentrySdk.CrashedLastRun`
