Consume fuel in array.new_default (#11428)

This commit updates the Cranelift-generated loop for `array.new_default`
to contain fuel/epoch checks. This ensures that large arrays have an
opportunity to context-switch away or otherwise interrupt the program to
prevent excessively long-running executions.

cc #11427 (does not solve it though)
