Replace the CLEAR_STATE approximation with the envelope and per-op-bit packet groups measured on PS5 firmware 13.60. Emit groups for op bits 0x001, 0x002, 0x004, 0x008, 0x010, 0x020, 0x080, 0x100 and 0x800 in ascending order; throw for 0x040, 0x200 and 0x400 whose packets the driver rejects. state 2 sets the envelope flag and state 3 sets the 0x004 and 0x800 group payload dword.
OpenAGC's include/agc_nids.h names three more of the raw-NID exports, and
each name hashes to its NID:
gQkqkLttcpw sceAgcAcb_gQkqkLttcpw -> sceAgcAcbAtomicGds_0900
dolOmWH+huQ sceAgcUnknownGetFusedShaderSize -> sceAgcGetFusedShaderSize_0080
V++UgBtQhn0 sceAgcGetDataPacketPayloadAddressUnk -> sceAgcGetDataPacketPayloadAddress_0090

Eight libSceAgc exports were published under a raw NID with a made-up
name. Each NID is the hash of a versioned SDK name (checked with
tools/nid_names.py compute_nid), so the functions now carry that name and
are exported from it directly:
23LRUSvYu1M sceAgcUnknownInitState -> sceAgcInit_0090
-KRzWekV120 sceAgcUnknown__MKRzWekV120 -> sceAgcDcbSetIndexSize_0600
Ikfdt-rIqCE sceAgcUnknown_Ikfdt_MrIqCE -> sceAgcJumpPatchSetTarget_0300
7Wa3aeJgeVU sceAgcUnknown_7Wa3aeJgeVU -> sceAgcBranchPatchSetThenTarget_0300
rP5xLdOf26k sceAgcUnknown_rP5xLdOf26k -> sceAgcBranchPatchSetElseTarget_0300
fd5Bp5tGTgo sceAgcUnknownFuseShaderHalves -> sceAgcFuseShaderHalves_0200
qj7QZpgr9Uw sceAgcDcbContextStateAnotherOp -> sceAgcDcbContextStateOp_0100
k0E7vkgqAuE sceAgcCreateInterpolantMappingVsPs -> sceAgcUpdateInterpolantMapping_0100
The exported NIDs are unchanged; the extra exports under the hashes of the
made-up names are gone. Behaviour is unchanged.

Every command writer checked bottom <= cursor_up <= cursor_down <= top.
PPSA16064 (Minecraft Dungeons II, Unreal Engine) builds small one-packet
buffers (8 dwords) with cursor_down left null, and the first
sceAgcDcbCopyData into one threw "invalid command buffer cursors".
Nothing in the library allocates downward, so cursor_down only bounds
the space above cursor_up. A null cursor_down now means that bound is
top. Non-null cursors are checked as before. TechnicalDebt records the
assumption.
agc_commands writes six dwords into such a buffer and checks that a
further allocation past top fails without moving the cursor.
Return the version 0 internal register defaults, the internal
counterpart of sceAgcGetRegisterDefaults.

Write the 2-dword CLEAR_STATE (0x12) packet with a 4-bit command, the
packet the driver already validates and executes by restoring the
initial context registers.

Patch the mask of a wait packet like sceAgcWaitRegMemPatchReference
patches its reference: a 32-bit value written to the low mask word of a
32- or 64-bit WAIT_REG_MEM, rejected above 32 bits.

WriteWait has truncated the reference and mask of a 32-bit wait since
9c2a7560 ("relaxed checks for what titles send"), but testMemory still
expected a reference above 32 bits to throw, so agc_command_tests failed
when run without arguments. ctest only registers the "defaults" mode, so
the stale expectation was never noticed.
Update the expectation to the truncating behaviour (the packet keeps the low
halves) and register the full mode as agc_commands so the packet, marker,
flip, register and memory cases are checked again.
Closes#1005.
A command buffer with fewer free dwords than reserved_dw (an empty one whose
title allocates its storage in the callback, as Marvel's Wolverine does)
threw "reserved space exceeds command buffer capacity" before its callback ran.
Its available space is now 0, so the allocation goes to the callback with the
reserved words added, as for any other full buffer.

sceAgcDcbDrawIndexIndirect and sceAgcDcbDrawIndexIndirectMulti emit
DRAW_INDEX_INDIRECT (0x25) and DRAW_INDEX_INDIRECT_MULTI (0x38) like their
non-indexed counterparts, with 20-byte records.
