Improve transaction setup for NextJS and caches

[Angelodaniel]

Problem Statement

I got a full-stack Next.js app that leverages a Cloudflare cache heavily.

We can currently see that by default Sentry tracks these 2 transactions:
GET / - server-side render
/<somepath - fired client side

One server-side render will map to many client-side renders (due to caching), if that changes anything.

For cases like these server -> client tracing is simply not a good idea. The traces will look horrendous most likely.
for now, we don’t have a workaround unfortunately but we’ll add an option to disable server -> client tracing for SSR.

Hey Angelo, were those ISR pages? We shipped a fix for them in v10.26.0 #18192 which should disassociate the ISR client transactions from the server transaction.
