hw/display/milkymist-tmu2: Move inlined code from header to source

Move the complexity of milkymist_tmu2_create() into the
source file. Doing so we avoid to include the X11/OpenGL
headers in all LM32 devices, and we also avoid the duplicate
declaration of glx_fbconfig_attr[] (it is already declared
in hw/display/milkymist-tmu2.c).
Since TYPE_MILKYMIST_TMU2 is now accessible, use it.
