This commit updates the type of the amount of times to inject fuel in the `out_of_fuel_async_yield` to `u64` instead of `u32`. This should allow effectively infinite fuel to get injected, even if a small amount of fuel is injected per iteration. Closes bytecodealliance#2927 Closes bytecodealliance#3046

Currently there is no way to configure an async store to run forever.
A fuel injection count has to be specified, which eventually reaches 0 and
causes a trap.
This changes the OutOfGas::InjectFuel configuration to make the injection
count optional, which allows stores to run forever.
NOTE: this is obviously a breaking API change.
It would also be possible to add an additional config method.
