* [AGC] Support multiple typed pixel outputs
Emit dense float, uint, and sint fragment outputs for sparse guest MRT slots. Preserve disabled components across partial exports, validate dense host locations, and retain the single-output compiler overload for compatibility.
* [Vulkan] Execute translated draws with multiple color attachments
Carry every active color target and its effective shader/register write mask through one Vulkan draw. Add per-attachment blending, independentBlend negotiation, device/format validation, multi-attachment synchronization, and safe image recreation after in-flight work completes.
* [ShaderDump] Add MRT edge-case coverage
Cover sparse mixed-type outputs, partial exports, merged partial exports, independent blend layouts, eight attachments, and invalid host locations. Run the synthetic shader suite in CI.

SelectPhysicalDevice took the first device exposing a graphics+present
queue. On hybrid-graphics laptops that is the integrated GPU, so the
discrete card went unused - and AMD's integrated driver access-violates
inside vkCreateGraphicsPipelines while compiling some translated guest
shaders, killing the process. The CLR surfaced that native AV as
"Invalid Program: attempted to call a UnmanagedCallersOnly method from
managed code", which made it look like a CPU/threading fault.
Score the candidates instead: NVIDIA parts win, other discrete GPUs come
next, and an integrated GPU is only chosen when nothing else can present.
SHARPEMU_VK_DEVICE=<substring> pins a specific adapter, and the selected
device is logged.
- Enable VertexPipelineStoresAndAtomics/FragmentStoresAndAtomics:
fixes vkCreateGraphicsPipelines() rejecting guestBuffers storage
descriptor as NonWritable in vertex/fragment stages.
- Enable ShaderInt64: fixes vkCreateShaderModule() rejecting SPIR-V
using 64-bit integer capability.
- Query GetPhysicalDeviceFeatures first and only enable what the GPU
actually reports as supported, with a warning fallback otherwise.
Also adds optional Vulkan Validation Layers (SHARPEMU_VK_VALIDATION=1)
to surface these VUID errors during development instead of silent
VK_ERROR_DEVICE_LOST.
* [shader-decoder-part1] Implemented a shader decoder for Gen5 shaders, including IR generation, metadata reading, scalar evaluation, and SPIR-V translation. Updated related exports and video output components to support the new shader decoding functionality.
* [shader decoder] correct RDNA2 operands, fixing synchronization problems
* [shader-decoder] RDNA2 decoder improvements
* [shader-decoder] fix RDNA2 shift masking and sprite draws
* [shader-decoder] improve RDNA2 shader decoder to support more instructions and fix some issues with the previous implementation.
