Merge #10988: qt: Increase BLOCK_CHAIN_SIZE constants

1967d2a qt: Increase BLOCK_CHAIN_SIZE constants (Wladimir J. van der Laan)

Pull request description:

  - Increase `BLOCK_CHAIN_SIZE` from 120GB to 150GB
  - Increase `CHAIN_STATE_SIZE` from 2GB to 4GB

  I took the local sizes of the blocks and chainstate directory, and added a bit extra to accomodate the near future (15GB for the chain and 1GB for the chainstate).
