[memfault] Manually inject faults when using stack allocations
Ensure that no assumptions are made that a small allocation will succeed
by manually injecting faults when we may be simply allocating from an
embedded memory pool.
The main advantage in manual fault injection is improved code coverage -
from within the test suite most allocations are handled by the embedded
memory pools.
