[WIN32SS] Use the DCFLAGS and DCTYPE flags defined in ntgdi/dc.h instead of the old ones in include/ntgdihdl.h master

The names of these new flags match the documented ones at https://reactos.org/wiki/Techwiki:Win32k/DC https://books.google.hr/books?id=-O92IIF1Bj4C&pg=PA197&lpg=PA197 and the gdikdx debug extension.
