ci(cm): add test configs to report max ctx memory usage

This patch adds two test configs that enable reporting
context memory usage.
It ensures all the context entries related feature flags are
enabled and reports the maximum memory consumption.

It has two variants:
* One works without SPMC at S-EL2 (no EL2 context)
* One works with SPMC at S-EL2 (EL2 context).
