feat(core): Hoist everything from @sentry/utils into @sentry/core

[lforst]

Ref #14269

This PR hoists the entirety of @sentry/utils into @sentry/core. Currently, nothing is deprecated. That will happen in a followup and after we have updated docs to not reference @sentry/utils.

In theory, this should not change any functionality whatsoever
