Deprecate integration-level tracePropagationTargets options in favour of top-level option

[Lms24]

Problem Statement

Our plans around the location of the tracePropagationTargets option have shifted a little. While in #6230 we opted direct people to use the integration-level TPT option, with the introduction of tracing without performance, we decided to add TPTs to the top-level Sentry.init options.

Solution Brainstorm

This means:

• Deprecate tracePropagationTargets in BrowserTracing
• Un-deprecate top-level tracePropagationTargets in Node
• Deprecate tracePropagationTargets in Http integration

We should do this soon to avoid more confusion!

Discovered this during hackweek (/getsentry/sentry-migr8#1).

Small update here:
Seems like I mistook the permalink from #6230 to be the current state of TPT in the Http integration. There it's already deprecated correctly. So all that's left is the deprecation in BrowserTracing which is addressed in #8874
