feat(remix): Add source map upload for Remix 3 (#24943)

Remix 3 has no build step and no output directory, so there is nothing
on disk for a source map upload to read.

`emitAssets()` rebuilds the output by driving the app's own asset
server: `getPreloads()` forces the browser module graph, and each
compiled module and its map is written out. The debug IDs are hashed
from the compiled source, so the emitted IDs match what the running
server serves.

The instrumented server hides source maps by default, so the emitter
reads them through the server's own fetch, which the stamping wrapper
now keeps reachable.

`sentry-remix-v3-upload-sourcemaps` is a separate bin from the Remix 2
`sentry-upload-sourcemaps`. It must run under `--import
@sentry/remix/v3/node`, which provides the TypeScript loader and patches
the asset server. Without it the emitted modules carry no debug IDs, so
the command fails on that rather than uploading an unusable set. This is
far from optimal but until we found a better solution this works.

The e2e test runs the bin against the app and checks that every module
has a map, each pair shares a debug ID, and the emitted entry's ID
equals the served one. It uses `--dry-run`: the CLI needs authentication
even for `inject`, so the upload itself is verified separately in
#24685.

Fixes #24678
