gui: Avoid redundant tx status updates

Browse Source 
In TransactionTablePriv::index, avoid calling
interfaces::Wallet::tryGetTxStatus if the status is up to date as of the most
recent NotifyBlockTip notification.  Store height from the most recent
notification in a new ClientModel::cachedNumBlocks variable in order to check
this.

This avoids floods of IPC traffic from tryGetTxStatus with #10102 when there
are a lot of transactions. It might also make the GUI a little more efficient
even when there is no IPC.
