sceGnmDrawInitToDefaultContextStateInternalSize previously threw NotImplemented_nid_no_patch.
Pinned shadPS4 2183807e59 (gnmdriver.cpp L2986-L2992) returns 0x20 below SDK 4.00 and 0x100
from SDK 4.00, matching the buffer sizes required by sceGnmDrawInitToDefaultContextStateInternalCommand.
Return 0x20 when the compiled SDK version in process parameters is below 0x04000000 and 0x100 from
0x04000000, reading the compiled SDK version at each call.
Below compiled SDK 0x04000000 the call writes sceGnmDrawInitToDefaultContextState's
19 words again, now that a run of firmware 13.42's module found them
byte-identical. The test pins the 19 words as literals.
sceGnmDrawInitToDefaultContextStateInternalCommand answers as
sceGnmDrawInitToDefaultContextState400 from compiled SDK 0x04000000, as a
native run of the firmware 13.42 module shows. Below it the run gave only
the result and length, not the words, so a call there throws.
