Remove fUseWTXID parameter from CBlockHeaderAndShortTxIDs constructor

Browse source 
All uses of CBlockHeaderAndShortTxIDs in the product code are
constructed with fUseWTXID=true, so remove the parameter.

There is one use of the CBlockHeaderAndShortTxIDs constructor with
fUseWTXID=false in the unit tests. This is used to construct a
CBlockHeaderAndShortTxIDs for a block with only the coinbase
transaction, so setting fUseWTXID to true or false makes no difference.

Suggested in https://github.com/bitcoin/bitcoin/pull/20799#pullrequestreview-963480278
