Fix CI/CD release skipping and Android linker errors

This commit addresses the issue where the CI/CD pipeline was skipping GitHub
Releases and not publishing packages, while also fixing Android linker errors.

Key changes:
1. Updated '.github/workflows/build.yml':
   - Added 'workflow_dispatch' for manual triggers.
   - Broadened triggers to all branches to ensure verification on feature branches.
   - Updated 'release' job condition to allow creation on any push or manual trigger.
   - Enforced Android API level 29 for better Vulkan 1.1 support.
2. Source code modifications for Vulkan portability:
   - Updated 'VulkanRTPipeline' to load 'vkGetPhysicalDeviceProperties2' dynamically
     using 'vkGetInstanceProcAddr', resolving linker errors on Android.
   - Updated 'main.cpp' to pass the Vulkan instance to the RT pipeline.
   - Guarded the 'main' entry point with '#ifndef ANDROID' for shared library builds.
3. Cross-platform improvements:
   - Properly guarded GLFW includes and window management for mobile support.
   - Optimized Vulkan external memory handles for non-Windows platforms.
