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.
