Add skeleton of ClMatMulLowpNativeMMULKernel

The skeleton code consists of modifications
   - to build the library with the quantized matmul kernel
   - refactoring of some common utilities
   - empty OpenCL Kernels for four configurations ([Lhs, Rhs] X [Nt, t])
   - some validation tests and skeleton for functional tests
