Replace the oneshot latency assumption with a 1ms periodic timer that
runs only across a forced dirty-partition erase, and fail if irq_count
falls below 80% of the expected count from erase duration.
Currently, several example dependencies rely on the fact that all
registered components are added to the build, along with components
specified in common requirements. This results in longer build times
because even unused components must be built. Switch all examples to use
idf_minimal_build to compile only the components actually required by
the example.
