RUM-5766 Pass correct privacy level to webviews

[mariedm]

What and why?

As part of the Fine-Grained Masking (FGM) initiative (see RFC), we have introduced new privacy levels for configuring Session Replay. We have an integration with the browser SDK, however, they don't support these fine-grained privacy levels. As a result, we need to ensure we pass the appropriate level to webviews.

How?

• Although the former privacy level has been deprecated, we still rely on it in WebViewTracking to pass the correct privacy level.
• Using the conversion matrix below, the new determineWebViewPrivacyLevel method converts the new privacy levels (text and input, image, touch) to the corresponding global privacy level.

Review checklist

• [x] Feature or bugfix MUST have appropriate tests (unit, integration)
• [x] Make sure each commit and the PR mention the Issue number or JIRA reference
• [ ] Add CHANGELOG entry for user facing changes
