* agc: implement sceAgcSetNop
Star Wars Outlaws calls sceAgcSetNop (K2mciNVxUCE) and crashes right after
the unresolved stub returns, without the packet being disabled.
The call turns a packet into a NOP of the same length. Clear the emulator's
custom NOP code as well, so packets that the HLE encodes as NOPs, such as
end-of-pipe actions, stop executing too.

* agc: keep packets disabled by sceAgcSetNop from reading as markers
A disabled packet whose first payload word carries the 0x6875 marker
signature still reached the marker handler, which can flip or stop on an
unknown marker ID. Clear the signature so the packet is skipped like any
other NOP.
