The "Semaphore poll/signal remains stable under host-thread contention"
test created the semaphore full (init == max == 1), so SignalSema could
only succeed after PollSema had already freed a slot. With no start
barrier, under host-thread contention the signaler thread could run all
64 of its iterations before the poller's first timeslice, making every
SignalSema legitimately return KE_SEMA_OVF and leaving signalOkCount at
0 — a false failure of "contended SignalSema should observe successful
releases". An earlier investigation of the unfixed test observed this
twice in 24 contended (8-way-parallel) full-suite runs and never in 20
serial runs; CI has independently hit the same assertion on the
unrelated draft PR #174, confirming the trigger is host scheduling, not
the code under review.
Seed the semaphore with headroom (init=1, max=2) so the first PollSema
and the first SignalSema each succeed regardless of scheduling order,
and add a start barrier so both workers start together, maximizing the
opportunity to interleave. Widen the final-count range check to the new
max. The semaphore implementation is unchanged; both threads still
contend concurrently on the same per-semaphore mutex.

* fix: semaphore syscalls return sid on success instead of KE_OK
The PS2 EE BIOS returns the semaphore ID on success for all semaphore
syscalls, not zero. PollSema, WaitSema, SignalSema, and DeleteSema were
all returning KE_OK (0) on success, which breaks games that compare the
return value against the semaphore ID.
DQ8's init code polls a mutex semaphore at 0x12A670 and checks the result
against the semaphore ID using bne. With KE_OK returned, the comparison
always fails and the game spins forever at PC 0x164978 and never starts.
Other games that follow the same EE BIOS convention would hit the same
problem. CreateSema already returned the ID correctly; this brings the
other four operations in line with the same convention.
The fix is five changes in Sync.cpp: the four return sites are updated to
return sid, and the count-decrement guard in WaitSema is changed from
ret == 0 to ret >= 0. The guard change is necessary because ret is now
seeded to sid (a positive value) on the success path, and the old equality
check would have silently stopped decrementing the semaphore count. Error
paths (KE_WAIT_DELETE, KE_RELEASE_WAIT) are negative and still correctly
bypass the decrement.
Tests are updated to expect sid instead of KE_OK on success paths, and new
test cases cover the blocked-wait-then-signal path (the actual DQ8 scenario),
force-release via ReleaseWaitThread, and the count-decrement guard directly.
* fix: update stale KE_OK assertions in expansion and SIF RPC tests
Two test files were not updated alongside the semaphore return-value change.
PollSema and SignalSema now return sid on success; update the four assertions
that expected KE_OK on those success paths.
* fix: tighten WaitSema count-decrement guard to ret == sid
ret is seeded to sid on success and only ever overwritten with negative
error codes, so ret == sid precisely expresses "this wait acquired this
semaphore" — more explicit than the looser ret >= 0.

* [runtime] Memory swizzling rework
Reimplementation of memory swizzling supporting all valid GS texture
storage types.
An additional optimization was done to improve the speed of lookups.
Since page access is linear, we can precompute the non-linear bit
(blocks and columns) for an entire page for each format. This reduces
the runtime calculation to just calculating the correct page in 2d
memory space and then performing a lookup in the table to get the
location in memory inside a page. Since all page accesses are the same,
this works across all pages. Speed improvements should be compounded by
the number of accesses but there might be some reductions as a result of
actually implementing formats that were not implemented before.
I took care to do this with simple math. GS swizzling is complicated and
optimizing it for debug builds is outside the scope of my current work.
This is just the standalone code. It will be worked into the current
rasterizer in a follow up commit.
