Automatically detect Vercel Edge Runtime and disable SDK accordingly

[lforst]

Problem Statement

The Next.js SDK crashes when run on the Vercel Edge Runtime. We have the means to check whether the SDK runs inside that runtime, so we can simply disable the SDK if that is the case.

Solution Brainstorm

As suggested by members of Vercel we could do a check like typeof EdgeRuntime !== "string" and just don't init.

@heldr Until we release the automatic fix for this use can use the excludeServerRoutes option to exclude vercel edge runtime routes from being instrumented with Sentry.
