[loader] cut import overhead (#32)

- 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.

-# Contributing
-
-Contributions are always welcome!
-
-Before opening a pull request, please keep the following in mind:
-
-- Keep PRs small and focused on a single topic.
-- Discuss large architectural changes before implementing them.
-- Follow the project's existing coding style.
-- Do not submit generated code unless you fully understand and can maintain it.
-- Do not introduce Sony proprietary code, firmware, keys, decrypted assets, or other copyrighted PlayStation materials.
-- All reverse engineering should be based on publicly available information, clean-room techniques, or your own original research.
-- Game-specific hacks should be avoided whenever possible. Prefer generic implementations that improve overall compatibility.
-- New features should not break existing behavior.
-- Ensure the project builds successfully before submitting a PR.
-
-If you're unsure about a design decision, feel free to open a discussion or draft PR first.
-
-## AI-Assisted Contributions
-
-AI-assisted development is welcome and may be used for research, reverse engineering, code generation, or documentation.
-
-However, contributors are expected to fully understand every line of code they submit. By opening a pull request, you confirm that you are able to explain, modify, debug, and maintain the submitted code without relying on the AI that generated it.
-
-When submitting an AI-assisted PR:
-
-- Clearly explain **what the change does**, **why it is needed**, and **what problem it solves**, using your own words.
-- Describe **how you verified the change**, including the games, applications, or test cases used.
-- Avoid excessive product-level logging. Use logging only when it provides meaningful diagnostic value.
-- Comments should document design decisions or implementation details in your own words. Avoid generic AI-generated comments that merely restate what the code already does.
-- Be prepared to answer review questions about the implementation. "The AI generated it" is not considered a sufficient explanation.
-- Large AI-generated changes without a clear understanding of the implementation are unlikely to be accepted.
-- If the implementation cannot be reasonably explained during code review, the pull request may be rejected regardless of whether it works.
-
-The quality, correctness, maintainability, and long-term ownership of the submitted code remain the responsibility of the contributor.
-
-## Coding Style
-
-SharpEmu follows a consistent coding style across the project. Please ensure your contributions match the existing style.
-
-- Use **4 spaces** for indentation (no tabs).
-- Use **2 spaces** for XML-based files (e.g. `.csproj`, `.props`, `.targets`, `.xml`, `yml`, GitHub workflow files where applicable).
-- Respect the project's `.editorconfig`.
-- Ensure every text file ends with a **single trailing newline**
-- Avoid formatting-only commits unless they are the purpose of the PR.
-- Keep naming, formatting, and file organization consistent with the surrounding code.
-- Prefer small, focused changes over large refactors.
-
-### REUSE Compliance
-
-This repository follows the REUSE Specification.
-
-Every new file must contain the appropriate SPDX license header. Pull requests that do not comply with the project's REUSE requirements will fail CI and will not be merged.
-
-### Recommended Development Environment
-
-The repository includes an `.editorconfig` and Visual Studio solution files.
-
-For the best experience, we recommend using:
-
-- Visual Studio Code with;
-  - C#
-  - C# Dev Kit
-
-Most editors that support `.editorconfig` will automatically apply the project's formatting rules.
