fix: Crash with AVAssetDownloadTask in setState

[itaybre]

Description

Fixes a regression introduced in 9.12.0 (#7588) where SentryNetworkTracker.urlSessionTask:setState: accesses sessionTask.originalRequest before the isTaskSupported: guard. AVAssetDownloadTask throws NSGenericException on that property, causing a 100% crash for any app using AVAssetDownloadURLSession.

The fix moves the isTaskSupported: check before the #if SENTRY_TARGET_REPLAY_SUPPORTED block that accesses originalRequest, restoring the guard order from 9.11.0.

Fixes #7886

How to test

1. Create an AVAssetDownloadURLSession and call makeAssetDownloadTask(...).resume()
2. Before this fix: crash with NSGenericException: AVAssetDownloadTask does not support originalRequest property
3. After this fix: task resumes without crash

Checklist

• I reviewed the submitted code
• I added applicable tests — verified in simulator that AVAssetDownloadTask no longer crashes
• No new PII or credentials are captured/stored
