Tracking Issue for -Zno-embed-metadata

[Kobzol]

Summary

Implementation: #15378
Documentation: https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#no-embed-metadata

The -Zno-embed-metadata flag tells Cargo to pass -Zembed-metadata=no to rustc, which saves disk space in the target directory, by avoiding generating duplicated metadata.

Unresolved Issues

• Is this a breaking change? Since rlibs/dylibs will not contain metadata after this change, it could break some users who depended on this.

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.
