feat: Implement structured logging for Unreal (all platforms)

[mujacica]

• Added support for Structured Logging in Unreal
• Integrated with Java/Cocoa/Native SDK features
• Added support for OnBeforeLog hook

---

Note

Adds structured logging across Android, Apple, and Native platforms with a new beforeLog hook, log APIs, settings, and output-device integration.

• Structured Logging (all platforms)
  • Add AddLog API to ISentrySubsystem and platform subsystems (Android/Apple/Native); route level-specific logs to SDKs.
  • Introduce beforeLog/BeforeSendLog callbacks (JNI/Cocoa/Native) and wire through bridges (SentryBridgeJava, JNI, Cocoa options).
  • Enable SDK logging via platform options (options.getLogs().setEnabled, options.enableLogs, sentry_options_set_enable_logs).
• Core API
  • New ISentryLog and USentryLog types; new USentryBeforeLogHandler for pre-processing logs.
  • Extend ISentrySubsystem::InitWithSettings to accept USentryBeforeLogHandler*.
• Settings
  • Add EnableStructuredLogging, category filters, per-level forwarding (FStructuredLoggingLevels), and "Also send breadcrumbs" toggle; propagate to platform init.
• Output Device
  • Update FSentryOutputDevice to forward UE_LOG to structured logging (with category filtering) and optionally send breadcrumbs.
• Android/Apple/Native internals
  • Add platform-specific log wrappers (FAndroidSentryLog, FAppleSentryLog, FGenericPlatformSentryLog) and HAL includes.
  • Add Java bridge methods for level-specific logging; Cocoa and Native use logger APIs.
• Misc
  • Update packaging scripts/snapshots and CHANGELOG entry for the new feature.

Hey @nwhite-riot, thanks for taking a look! I will address your code comments in the next rev, but on a more general note: yes we want this enabled on consoles too, but what was meant with “all platforms” is all platforms in this repo. As soon as this PR is done, I am going to follow up with all console plugin integrations in other repos (breaking changes for init).

Regarding naming: as you might see I was trying different things out, but sticking with one name makes more sense. I will think about it a little more.
