Several error handling patterns in Modules/_remote_debugging/ need cleanup:

• Missing error checks on some code paths (e.g., varint decoding, memory allocation failures)
• Inconsistent error propagation across platforms
• A couple of reference counting issues on error paths

Working on a fix.

   I think these fixes still need to be backported 3.14, but that needs to be done by hand since #141934 was not backported
