Minor fixes for working with GAMG, minor optimizations

Remove the -pc_gamg_symmetrize_graph option completely. Use symmetric state of matrix

Combine MatCreateGraph() and MatFilter().

Minor optimizations of MatCreateGraph() when numerical values are not needed skip abs(entries) and dscale (for MIS and MISK)

Add PCGAMGCreateGraph() function

TODO: when using MIS and MISK only structural symmetry of matrix is needed, not actual symmetry
