chore: Add size limit reports on PRs for Cloudflare

[JPeer264]

Cloudflare does have a free tier limit of 3mb: https://developers.cloudflare.com/workers/platform/limits/#worker-size

It would be too bad if we ship something for Cloudflare and by accident ship something which is super costly.

wrangler bundles in esbuild, so we have to add the esbuild plugin, but we need to disable esbuild for other builds to keep bundle the rest in webpack. Which is why I disabled esbuild everywhere, except for Cloudflare. size-limit defaults to esbuild if enabled

looks like some other commits made it to this branch 🤔 😅

also, no objections to adding a size limit entry! Just to check: when you add the SDK to cloudflare workers (or other components): Does this roughly equate to the same size? Just wondering if we're missing any dependencies/node_modules data that might make the SDK's footprint larger in reality than the size check shows

[JPeer264]

Ok the auto rebase function from GitHub doesn't work as expected :D

Theoretically we are depending on @sentry/core and maybe in the future @sentry/node or @sentry/node-core. Wouldn't that be automatically added here?

There is indeed something missing. I'll try to add it

[JPeer264]

Converting to draft, as for Cloudflare we have to use esbuild to show the actual numbers. Unfortunately size-limit only accepts one bundler at a time, which means that the others have to use esbuild as well.

I opened an issue to see if it would be possible to have two bundlers in one size-limit file
