ref(tracing-internal): Deprecate tracePropagationTargets in BrowserTracing (#8874)

This PR deprecates `BrowserTracing`'s `tracePropagationTargets` option
in favour of the top-level Sentry.init option.

When introducing Tracing without Performance, we opted to [promote
`tracePropagationTargets` to a top-level
option](#8395). We
deprecated the integration-level option in Node's `Http` integration but
not in `BrowserTracing`. This patch fixes that.
