[RUMF-1068] Forward browser_sdk_version to mobile

[amortemousque]

Motivation

The mobile SDKs (Android and iOS) want to track events that happen inside a webView using the browser SDK. The proposed way to do that is to inject a JS bridge interface that the browser SDK will call instead of sending the events to the intake.

To easily monitor browser sdk event sent though mobile, we need to keep the browser SDK version tag.
Because it is not easy for the mobile to keep browser tag, this first version send it as _dd attribute.

Changes

Add browser_sdk_version in _dd

Testing

• Local
• Staging
