Allow users to run readout benchmarking with sweep

[ddddddanni]

Requested by @NoureldinYosri, this pr is splited from https://github.com/quantumlib/Cirq/pull/7358.

The pr adds a new function run_sweep_with_readout_benchmarking which runs the sweep circuits with readout error benchmarking (without shuffling).

cc: @eliottrosenberg this is a smaller RP I split from https://github.com/quantumlib/Cirq/pull/7358. This one only touches the readout benchmarking but not pauli expectation calculation.
