Fix batch execute with pasqal device

[albi3ro]

cirq.Circuit no longer has a device argument.

This wasn't caught as the reset method was not being tested for the pasqal device. This PR also adds a test that will execute multiple circuits.

I also started converting control_radius to a float so we can start using cirq.pasqal in the automatic test matrix.

should we add a test for reset on that device now too?

covered now by testing batch_execute with a batch. Also by putting it in the device test suite.
