Refs #462. The reporter confirmed that the VK_ERROR_OUT_OF_HOST_MEMORY pipeline failures in Ocarina of Time's intro come from the Windows commit limit. A Switch 2 game commits 14 GiB of guest memory when it starts (SEC_COMMIT in common/host_memory.cpp), and the intro compiles several very large shaders at once. With 16 GB of RAM and a 16 GB page file (31.9 GB commit limit), 25 pipelines failed and the game then aborted. With the page file enlarged (53.9 GB), none failed in three runs. Today this failure only shows as a black video and a log line that says "Adreno rejected compute shader" on every GPU.
Changes
The compute failure log line says "Driver rejected compute shader" instead of "Adreno rejected compute shader".
When a compute or graphics pipeline build fails with VK_ERROR_OUT_OF_HOST_MEMORY, a new ReportPipelineBuildFailure logs once per session what that means. On Windows it includes the current system-wide commit and limit (from GetPerformanceInfo, through the existing Common::GetProcessMemoryUsage), for example "Windows commit is 31.8 of 31.9 GiB", and says to enlarge the page file if commit is near the limit. Running out of host memory alone doesn't prove the limit was reached. Other error codes are unchanged.
docs/user/Troubleshoot.md gets a section on this failure: symptoms, cause, and how to enlarge the page file and check Committed in Task Manager. docs/nx2/amd.md links to it from "Settings for AMD users", since GPUs without matrix cores (where Ocarina's tensor-core shaders are emulated) are the ones that hit it.
No behaviour change: failed pipelines are handled exactly as before.
Testing: builds with clang on Linux, and the full tests suite passes (1090 cases). The Windows branch of pipeline_build_failure.cpp passes a syntax check with MinGW g++. I couldn't trigger an out-of-memory failure here, so the new message itself is untested at runtime.

A Switch 2 game commits 14 GiB of guest memory at start, so on 16 GB
Windows hosts with a small page file the driver fails Ocarina's intro
pipelines with VK_ERROR_OUT_OF_HOST_MEMORY. Log once what that means,
with the system commit figures on Windows, and say "Driver" instead of
"Adreno" in the compute failure line. Document the page file fix.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The change adds reporting for Vulkan pipeline-build failures caused by host-memory errors. It also documents Windows page-file guidance and system commit-limit conditions associated with shader compilation failures.
A new reporting function logs the first VK_ERROR_OUT_OF_HOST_MEMORY result. On Windows, it includes system commit usage and limit when the memory query succeeds; otherwise, it logs a fallback message. Compute and graphics pipeline failure paths call the function.
Document Windows commit-limit conditions docs/user/Troubleshoot.md, docs/nx2/amd.md
The troubleshooting and AMD settings pages describe Windows page-file guidance and system commit-limit conditions associated with shader compilation failures.

Explanation
The title names the main change: the PR adds an explanation (a once-per-session log message and troubleshooting docs) for VK_ERROR_OUT_OF_HOST_MEMORY pipeline build failures, tied to the Windows commit limit and issue #462. The changeset adds pipeline_build_failure.cpp/.h, wires ReportPipelineBuildFailure into the compute and graphics pipeline code, and adds Windows guidance in docs/user/Troubleshoot.md and docs/nx2/amd.md. The title is concise, specific, and matches the changes. It does not mention the Adreno-to-driver wording change, but that is a minor secondary edit.

video_core/vulkan_common/vulkan.h enables VK_USE_PLATFORM_XLIB_KHR on
Linux, which pulls in <X11/Xlib.h> and its `#define Success 0`. Included
first in vk_compute_pipeline.cpp and vk_graphics_pipeline.cpp, it broke
NvResult::Success in nvdata.h on the GCC 13 build. VkResult only needs
vulkan_core.h, as vulkan_wrapper.h already does.

Recommend a 32 GB initial size with a maximum of at least 48 GB, instead
of fixing both at 32 GB, so the guide never lowers an existing maximum

Use system-wide commit values in the diagnostic.
When Windows reports a lower process commit limit or availability, these fields can produce figures that do not describe system commit. The message can then direct users to enlarge the page file even when the system has commit available. Use GetPerformanceInfo for system commit and limit, with a fallback if the call fails.

GlobalMemoryStatusEx's page file fields are the process's commit limit
when that is lower than the system's. GetProcessMemoryUsage already reads
the system commit and limit through GetPerformanceInfo.

system commit is near the limit. Keep the existing memory measurements, and
avoid implying that a nonzero limit or VK_ERROR_OUT_OF_HOST_MEMORY proves system
