Add benchmark tests for TMVA Sofie

[lmoneta]

Ann new tests for TMVA SOFIE including tests using ONNXRuntime and LWTNN

Add corresponding Find.. cmake modules to find the needed package Make also use of FindBLAS to find teh correct BLAS version. Need to use -DBLA_VENDOR to configure to the right BLAS type installed in the system. For example -DBLA_VENDOR= -DBLA_VENDOR=Intel10_64lp_seq to use the sequential MKL library that is used in the benchmark presented at ACAT
