Merge bitcoin/bitcoin#31215: rpc: increase the defaults for -rpcthreads and -rpcworkqueue

Browse source 
e56fc7ce6a rpc: increase the defaults for -rpcthreads and -rpcworkqueue (Vasil Dimov)

Pull request description:

  `rpcthreads` was introduced with a default of 4 in 2013 in 21eb5adadb

  `rpcworkqueue` was introduced with a default of 16 in 2015 in 40b556d374

  Resolves: https://github.com/bitcoin/bitcoin/issues/29386

  Just bump the ancient default values. There is no perfect default that would fit everybody. This could lead to https://bikeshed.com/
