feat: change to create chCheckTx with the value set in app config.

[zemyblue]

Description

Change to create chCheckTx with the value set in app config.

Basically, chCheckTx of BaseApp should be equals to or greater than mempool size.
But when running NewBaseApp, the mempool size can not know.
So I add the feature set the size of chCheckTx as config

So following features have been changed

• add chCheckTxSize in Baseapp
• add FlagChanCheckTxSize flag as cmd flag
• add chan-check-tx-size field in app config.
• set default chanCheckTxSize to 10000.

closes: #753
