Refactor of `experienceHandler/Capability`.

[mfrankov]

• Adds the ability to interact directly with the IExperienceStorage to BasePedestalBlockEntity to reduce the need to interact with LazyOptionals within your own class.
• Renames the existing LazyOptional value to experienceCapability which is only used within the getCapabilities.
• Updates sendExperienceToPedestal to use the LazyOptional.map method and a lambda function to make it perhaps slightly clearer to read.

The same changes as outlined above, but for energyCapability.

The same changes as outlined above, but for dustCapability.

• This one was a bit more involved around fill. Given you returned 0 for !storedDust.isDustEqual(dust) regardless of the simulate action, pulled that into the first test. Then pulled out the replicated computation around filtering into dustAmountPostFilter. Finally folded together the simulate/not-simulate cases by pulling in the if (!action.simulate()) check into the appropriate blocks.

The same changes as outlined above, but for fluidCapability.

• As with dustCapability this was more involved in fill given a lot of redundant checks being folded together. Also, like with dustCapability there's a nuance in drain where you need to copy what is being removed before calling shrink (I added a comment this time as a reminder for the future).

I wasn't as able to test the dustHandler in my setup, but I tested this with a FluidPump pedestal connected to a Drain pedestal (each with just 1 work area below the pedestal, and confirmed if you transfer multiple buckets from the Pump that the Drain waits/buffers the extra fluid and later places it if you pick up the fluid sources from in-world).
