MemBrowse memory footprint tracking in CI (Following a discussion with wolfSSL team)

I've configured four targets in membrowse-targets.json, all on Cortex-M4 with minimal test code linked so it doesn't affect the memory tracking:

• gcc-arm-cortex-m4
• gcc-arm-cortex-m4-baremetal
• gcc-arm-cortex-m4-min-ecc
• gcc-arm-cortex-m4-tls12

It includes:

• membrowse-targets.json - defines the build targets with setup and build commands
• membrowse-report.yml - runs on every push to master and on PRs
• membrowse-comment.yml - comments on PRs with a memory usage summary
• membrowse-onboard.yml - one-time workflow to load historical reports

To get started:

1. Create an account at membrowse.com
2. Create a project to get an API key.
3. Set it as a GitHub secret called MEMBROWSE_API_KEY

The workflows will handle the rest.

Full docs are available at docs.membrowse.com.

Happy to help if any questions come up during integration.

Can one of the admins verify this patch?

Create a project for wolfssl on membrowse.com so the report jobs would not fail :)
