This patch refactors GPU shaders to remove includes to the utility gpu_shader_common_math.glsl file. This is done because it has duplicate functions that exist in other files, and it was really created for use in GPU material nodes. The safe_divide and hypot functions were removed since they exist in gpu_shader_math_base_lib.glsl. The compatible_[mod|pow] and wrap functions were moved into gpu_shader_math_base_lib.glsl. The floor_to_int function was inlined since it was trivial and only used in one place. The quick_floor was removed because it was unused. The euler_to_mat3 function was replaced with the from_rotation function from gpu_shader_math_matrix_lib.glsl. Now the file only contains some GPU material node utility functions.
