Ruben Fiszel 8417c5b792 chore: split debug info for EE release builds (#8396)
* chore: split debug info for EE release builds

Generate line-table debug info in release builds and split it into
a separate .debug file. The shipped binary remains stripped (same
size as before), while the .debug files are attached to GitHub
releases for both amd64 and arm64 EE builds.

This enables production debugging with gdb/perf by copying the
matching .debug file into a running pod.

* chore: extract debug info via separate Docker stage

Use a `FROM scratch AS debuginfo` stage instead of copying the .debug
file to the final image. This keeps the shipped image at exactly the
same size as before. CI extracts the .debug file using depot's
--target debuginfo with cache hits from the main build.

Also adds gnu_debuglink so gdb auto-discovers the debug file when
placed next to the binary.
