feat(tracing|core): Remove transaction name change recording

[AbhiPrasad]

The bundle size king strikes again.

In #5679 we added functionality to track transaction name changes. This was used to collect data about transaction name quality in the SDK.

In getsentry/relay#1671 we removed from relay the tracking of these name change metrics, so let's also remove them from the SDK.
