[PATCH RFC 00/11] rust: add support for dynamic debug

Add the Rust infrastructure to integrate with the dynamic debug
infrastructure.

Static keys are not used for now, as the full bindings are missing
for those. A follow-up series will add that.
Also custom classes are not supported yet, but could be added on top.

Patches 1-4: Generic Rust preparation patches.
Patches 5-7: C dynamic debug preparation patches.
Patches 8: Rust Dynamic debug infrastructure.
Patches 9-11: Rust Dynamic debug enablement.
