fix(tests): load AGC libraries for the pipeline-clear regression on Windows

[simonbronk]

What

Follow-up to #6814; please merge it first. Its original commit 81e3db853c00453a04668e2c62e8b969f24d324b is preserved unchanged with its original authorship. Only the final commit is this Windows test-registration correction; until #6814 merges, the diff also contains that PR.

The new agc_pipeline_library_clear_waits_for_build test does not receive the Windows DLL search path that its neighbouring agc_pipeline_journal test uses. On Windows its CTest invocation timed out after 30.02 seconds; launching with the same missing DLL directory exits with 0xC0000135. The identical executable succeeds with the directory available.

Add the new test to the existing WIN32 PATH property. No runtime or timeout change.

Tested

Windows x64, supported WinLibs MinGW-w64 GCC 15.2.0 r7 UCRT, CMake 4.4.4, Release, BUILD_TESTING=ON, SPIRV-Tools disabled. Current main 82ddae75b6761757f3d3ba9c0723647469270f76, parent #6814 81e3db853c00453a04668e2c62e8b969f24d324b.

• Built the actual libSceAgcDriver.prx, dependencies and graphics test executable. No CPU-guard bypass or production instrumentation.
• Before this follow-up: agc_driver_graphics and agc_pipeline_journal pass; the new official regression times out. Two independent mocked-Vulkan controls against the actual DLL pass on fix(agc): drain library prebuilds before device replacement #6814 and fail on main: clear during a library-part creation error and during a final-link error. They also check unrelated-device progress and rebuilding after clear. These controls are provided as an external fixture, not added to this PR.
• With the PATH correction: the five-test composition passes, and the official regression plus both independent controls pass ten times each (30 executions).
• Final verification removes the private fixture from the checkout: the exact publishable tree edbb564ebdb1bf30b8788d12c972292e5b0368bf passes agc_driver_graphics, agc_pipeline_journal and agc_pipeline_library_clear_waits_for_build (3/3). Conventions pass.
• CPU/mock tests only. No real Vulkan/GPU, Stray, console, Linux/macOS, complete all-target build or full CTest run. The Stray crash and title results belong to AGC: since #5875, a registration library prebuild racing the window attach segfaults in LinkPipelineFromLibraries (Stray PPSA02100, warm shader cache) #6805/fix(agc): drain library prebuilds before device replacement #6814, not a local title run.

Checklist

• Based on current main plus fix(agc): drain library prebuilds before device replacement #6814; no duplicate Windows test-path correction found
• One topic per PR; follow-up is a separate PR
• No code comments added
• No changes to unimplemented paths or silent stubs
• No investigation files added to the repository
• No new third-party code
• Generic test configuration, not title-specific
• Depends on: fix(agc): drain library prebuilds before device replacement #6814
• Unblocks: none (validates the regression for AGC: since #5875, a registration library prebuild racing the window attach segfaults in LinkPipelineFromLibraries (Stray PPSA02100, warm shader cache) #6805, Stray PPSA02100)
• GPUs tested: none (CPU/mock tests only)
• AI-assisted: yes (OpenAI Codex; parent retains its original AI disclosure)

@simonbronk @MarcZX100 The updated #6814 already contains this Windows registration correction. I fetched both published heads and verified that #6814 83eb3ed04ae2307f494da08010f123dcb165f861 and this PR 17647ac7f56b4d2ed5fe24efd0d91e792af00103 have the same complete Git tree, edbb564ebdb1bf30b8788d12c972292e5b0368bf; git diff between them is empty.

That is also the exact publishable tree named in this PR's Windows verification report. Those reported Windows results therefore cover the same file contents as the updated parent; this is a source-identity check, not another execution on my machine or a new current-main build claim.

There is no remaining file difference for this follow-up to contribute after #6814. Consolidating into #6814 appears appropriate. No PR or branch was modified by this check.

[blawesom]

Duplicate pair heads-up for the maintainers: this PR and #6814 carry byte-identical diffs (217 lines across the same six files — ShaderRegistry.hpp/.cpp, VulkanDevice.cpp, PipelineLibrary.cpp, the CMakeLists and Graphics.cpp — both adding AwaitLibraryPrebuilds()). #6814 was opened first (13:03 UTC); this one followed 28 minutes later. Whichever survives, the other can be closed as a duplicate — flagging both rather than choosing, since the call is yours.

[oneandonlydean]

Closing in favour of #6814, which carries the same change, including this PR's Windows test fix, and is being tested on current main.
