[shader-decoder-part1-hotfix] New format support, maintenance8 support, robustness improvements, and bug fixes. This commit includes updates to the AGC exports, Gen5 SPIR-V translator, and Vulkan video presenter to enhance compatibility and performance. (#31)

- 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.
