Add the unversioned sceAgcCreateInterpolantMapping and
sceAgcUpdateInterpolantMapping and stop sceAgcUpdateInterpolantMapping_10000
throwing for split f16 defaults, all matching libSceAgc bit for bit.

Write the INDEX_ATTRIBUTES_INDIRECT packet the console's builder writes,
as measured by the prosper console oracle, with OpenAGC's signature, and
report its measured size of 16 bytes.

The names hash to the NIDs dbOlWdppb4o and vieBRwlh1Lw that the exports
carried as sceAgcUnknownCreateInterpolantMapping and
sceAgcUnknown_vieBRwlh1Lw.

sceAgcSetAmmSemaphoreMemory(memory, sizeInBytes) registers the AMM semaphore memory once and zeroes the first 8 bytes of each 32-byte label; sceAgcGetSemaphoreLabel(index, label) writes memory + 32 * index for an index inside the registered memory.
Unblocks New Joe & Mac Caveman Ninja (PPSA02801) which imports both symbols. Matches OpenAGC and sharpemu agreements on signatures, 16 KiB alignment, 32-byte stride, and zeroed label counters.
sceAgcDcbSetWorkloadStreamInactive and the three ACB workload builders
(sceAgcAcbSetWorkloadsActive, sceAgcAcbSetWorkloadComplete,
sceAgcAcbSetWorkloadStreamInactive) threw for every call, and
sceAgcDcbSetWorkloadsActive read the workload ids before it checked the
stream.
The prosper console oracle (mattias800/prosper df074498,
prosper/tests/data/console_oracle/agcbuild.golden.tsv lines 48-56 and
196-204) measured all six calls on a PS5 with three argument patterns
and no workload stream registered: each returned null and wrote nothing.
Pattern b passes stream 1 with the workload ids at address 2, so the
console checks the stream before it reads the ids; here that call read
address 2 and crashed.
The four builders now return null for a null command buffer or a stream
that is not registered, and still throw for a registered stream: the
packet a registered stream gets is not measured, KytyPS5 has no body for
them, and its IT_NOP layout for the DCB calls differs from the
SET_UCONFIG_REG, WRITE_DATA and SET_WORKLOAD sequence OpenAGC
(3c7e8072, src/agc_workload_packet.c) derives from the driver. The
signatures are OpenAGC's DCB ones (src/game_compat.c), which says the
ACB calls use the same driver builders. sceAgcDcbSetWorkloadsActive now
checks the stream before the ids, as OpenAGC does. Recorded in
docs/dev/debt/libSceAgc.md.
agc_commands gains testWorkloadStreams: the three measured patterns for
all six calls (null, buffer untouched), an exhausted and a null buffer,
and a registered stream that throws without touching the buffer. On
upstream/main it fails with "sceAgcDcbSetWorkloadStreamInactive not
implemented", and the DCB active pattern b alone segfaults reading
0x2.
