Align PyBaMM simulation methods

[NicolaCourtier]

Description

Remove the custom build process for PyBaMM simulations without an experimental protocol. The aim is to improve maintainability by always using the build process provided by PyBaMM's Simulation class.

Also, change batch_solve to solve_batch to align with other function names such as evaluate_batch. Deprecate some of the warning/error catches that no longer appear to be needed.

Fixes #783
