.sync/Makefile.toml: Check and test without default features

[makubacki]

Without --no-default-features testing, feature-gate regressions go undetected. Code that accidentally uses a gated module or dependency outside its cfg fence compiles fine under default features but breaks for consumers that disable defaults.

Adds a higher level check-no-default-features task with two parallel subtasks:

• check-no-default-features-code:
  • cargo check --no-default-features
• check-no-default-features-tests:
  • cargo test --no-run --no-default-features

Runs the task in cargo make all.

Makefile-patina-readiness-tool.toml is not updated since it doesn't have a current check task and won't benefit much from this change.

The change in the patina repo will be merged in OpenDevicePartnership/patina#1404. The patina Makefile.toml changes in this PR exactly match that change.

We probably want an additional step in CI to run the one that compiles with no features

To make sure I understand correctly, are you suggesting that check-no-default-features is sufficient in the all task from a sanity check perspective, but we have another step (outside of all that is already called today in CI) that invokes cargo test --no-default-features (because --no-run is in check-no-default-features)?

To make sure I understand correctly...

I spoke to Joey offline. I assumed that we run cargo make all in CI like some other repos, but that's not the case. I will add it to the CI steps.
