[config] Remove blockmaxsize option

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.
