Add codegen backends to RooFit backend fit benchmarks - #310

Benchmark the automatic-differentiation "codegen" evaluation backend and its "codegen_no_grad" variant (numeric gradient) alongside the existing Legacy, CPU, and CUDA configurations. The GausXS model gets no codegen variants because its normalization requires a multi-dimensional numeric integral that the codegen backend does not support. The BDecay benchmarks in RooFitUnBinnedBenchmarks.cxx are also left unchanged, since RooBMixDecay, RooGaussModel, and RooAddModel have no codegen translate functions yet. This supersedes the corresponding part of PR root-project#282.
