Ignore-list internal frames whose source maps chain to original sources (#95448)
Next's dev error output (terminal logs and the browser overlay)
ignore-lists framework-internal stack frames. The forked
`EvalSourceMapDevToolPlugin` recomputes this ignore-list per module
because the vendored `webpack-sources` has no runtime `ignoreList`
support, so it drops the field when it combines a module's input source
map with the generated mappings. `shouldIgnorePath` matches on the
emitted source path, which works while a source resolves back to its
module. But a Next-internal module that ships an input source map (its
`.js.map`, which taskfile-swc marks entirely ignore-listed) resolves its
sources to the original files such as `src/server/web/adapter.ts`, which
no longer contain the `node_modules`/`next/dist` marker and no longer
resolve back to a module. Those frames then escape ignore-listing and
leak into both the terminal output and the overlay.
For such unresolved sources this falls back to the module's own resource
path, so a frame whose module lives in `node_modules`/`next/dist` stays
ignore-listed even when its source map points at the original source.
The fallback applies only to a `NormalModule`, whose sources all belong
to that one module; a `ConcatenatedModule` merges several modules'
sources under one map and is left to the path check, which the dev
`eval-source-map` devtool never produces anyway.
