Reduce memory/cache overhead from over loader processing

[ijjk]

In v14.0.2-canary.1 users started noticing more memory errors especially with many edge runtime configured pages. After investigation it seems this can be related to the additional transpiling we configured in #59569 and #57784

To help alleviate this we are updating the default swc loader to have an additional check to see if no special features such as next/font, next/dynamic, or use server/client directives are present and then no-oping in the loader to avoid additional overhead for a majority of modules.

For monitoring regressions our stats-app has been updated with repeated edge-ssr routes to hopefully help us keep an eye on memory or cache size issues.

These are intentional to stress test compiling numerous edge app routes.
