chore(ci): Extend compiler memory report to external repos

[vezenovm]

Description

Problem*

Followup to #6750

Summary*

This report essentially copies the process in #6750 for recording additional benchmarks from external repos. I made two new jobs external_repo_memory_report and upload_memory_report. I debating making the uploading and the uploading of the compilation report to be one job but I decided it would be better to keep them separate.

Additional Context

The memory report job for noir-contracts takes ~29 minutes with ~9G for peak memory. I commented it out for now due to the time it takes and was not sure we would want to be running this on every job.

I was thinking it may be best to simply generate benchmark reports for external repos only when specified by the label run-external-checks, similar to our testing of external repos.

Documentation*

Check one:

• No documentation needed.
• Documentation included in this PR.
• [For Experimental Features] Documentation to be submitted in a separate PR.

PR Checklist*

• I have tested the changes locally.
• I have formatted the changes with Prettier and/or cargo fmt on default settings.
