Improve tracing

[stayallive]

• Nest view.render spans
• Nest sql.query spans
• Add 2 child spans to http.server
  • app.bootstrap the Laravel bootstrap process
  • app.handle (please suggest a better name) which will have all other spans that are generated by the user application as childs
• Only boot the tracing provider if there was a hint of a DSN (like the Sentry SDK itself)
• Move all tracing related events to it's own event handler
