Add breadcrumbs on network changes

[stefanosiano]

📜 Description

added NetworkBreadcrumbsIntegration
added registerNetworkCallback and unregisterNetworkCallback to ConnectivityChecker
added io.sentry.breadcrumbs.network-events manifest option
added enableNetworkEventBreadcrumbs manual option

💡 Motivation and Context

In order to provide more context to the user when an error occurs or during a transaction, we are adding breadcrumbs on network changes, like when a vpn is enabled or disabled or the device connects/disconnects to/from a network.

💚 How did you test it?

Unit tests

📝 Checklist

• I reviewed the submitted code.
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

Connection details (vpn status, up/down bandwidth and signal strength) is collected correctly and set as a Hint of the breadcrumbs. I should add these details to the breadcrumb data, too
