Henrik RydgårdandClaude Opus 5.5 9f1278b5d6 iOS: Link MoltenVK statically in sideload builds too, raise target to 15.0 
Sideload builds used to dlopen a bundled libMoltenVK.dylib, which was
only worth having while they could still fall back to OpenGL. Now both
variants link the static MoltenVK from ios/MoltenVK and call Vulkan
directly. PPSSPP_VK_STATIC replaces the IOS_APP_STORE checks in the
Vulkan loader (the iOS libretro core still loads at runtime).

The static MoltenVK needs iOS 15.0, so that's now the deployment target
for all iOS builds.
