x/pkgsite: track JS errors and latency metrics via Google Tag Manager #40958
https://philipwalton.com/articles/the-google-analytics-setup-i-use-on-every-site-i-build/ has some good info for tracking JS errors and latency metrics via Google Analytics. Since we use GTM we have to pipe the info through there.
As a note, we should not implement all recommendations in the doc above like recording client and window IDs.
Also worth looking into https://web.dev/vitals/ to see if those are more appropriate to record as well.
The implementation details can be outlined in this issue or a public doc (plus the CL will be public).

…king Adds the web vitals script built from source to track web vitals metrics with Google Tag Manager. This will give us more insight into how pkgsite is performing in the wild and allow us to track changes in performance before and after the redesign.

Adds a flag to disable CSP during local development. Useful for debugging Google Tag Manager configuration.
