Merge #12756: [config] Remove blockmaxsize option

Browse source 
4757c04 [config] Remove blockmaxsize option (John Newbery)

Pull request description:

  The blockmaxsize option was marked as deprecated in V0.15.1, and code
  was added to convert provided blockmaxsize into blockmaxweight. However,
  this code was incorrectly implemented, and blockmaxsize was silently
  ignored.

  No users have complained about blockmaxsize being ignored, so just
  remove it in V0.17.

  Fixes #12640

Miner block size removed
------------------------
The `-blockmaxsize` option for miners to limit their blocks' sizes was
deprecated in V0.15.1, and has now been removed. Miners should use the
`-blockmaxweight` option if they want to limit the weight of their blocks'
weights.
