fips: Reorder self-tests by complexity

fips: Reorder self-tests by complexity

Reorganize the FIPS self-tests to group them by complexity.

The new order groups tests so that more complex ones are executed before
less complex one when all tests are run on_demand, improving the odds
that lower level tests are implicitly executed as part of higher level
tests and therefore reducing the amount of time spent running redundant
tests.
