Merge #13216: [Qt] implements concept for different disk sizes on intro

9d0e52834 implements different disk sizes for different networks on intro (marcoagner)

Pull request description:

  Fixes https://github.com/bitcoin/bitcoin/issues/13213.
  Mostly, I layed out the concept to open the PR for refinement and getting feedback if the approach is okay. Changes are expected.

  Two points:
  - The values for both new consts `TESTNET_BLOCK_CHAIN_SIZE` and `TESTNET_CHAIN_STATE_SIZE` is certainly not optimal; I just checked the size of my testnet3 related dirs and set them to little bit higher values. Which values should be used?
  - Should we do something like this to regtest? Or these "niceties" do not matter when on regtest?

  Thanks!
