Fix bugs in RBF Mapper

This PR fixes several issues identified in the Radial Basis Function (RBF) mapper in the MappingApplication.

Changes

• Fix incorrect reading of the parameter use_all_rbf_support_points from the input settings.
• Add a new parameter global_space_dimension, required to correctly define the polynomial augmentation of the RBF system.
• Fix potential singularity in the interpolation matrix when using a 3D polynomial basis in 2D cases, which previously introduced a row of zeros.
