Based on the discussion in #7723, make the CheckTx benchmark exercise GetEvictableTxs which is one of the critical paths in CheckTx. After profiling the test, the sorting will occupy 90% of the CPU time in CheckTx. In the test it doesn't count the influence of the preCheck, postCheck, and CheckTxAsync when the mempool is full.
