Disassociate batching from the data arg to solve and remove data

[Vaibhavdixit02]

The data handling is quite awkward leading to issues like SciML/OptimizationBase.jl#13, without batching data doesn't need to be passed in specially and should be a part of p to avoid global variables and in case of batching the right way would be to have support for stochastic oracles discussed in SciML/OptimizationBase.jl#61.
