Bumps MoltenVK to 1.2.5 matching Vulkan SDK 1.3.261

Changelog:

• Add support for extensions:
  • VK_KHR_incremental_present
  • VK_KHR_shader_non_semantic_info
  • VK_EXT_4444_formats
  • VK_EXT_calibrated_timestamps
  • VK_EXT_pipeline_creation_feedback
  • VK_EXT_shader_demote_to_helper_invocation
  • VK_EXT_shader_subgroup_ballot
  • VK_EXT_shader_subgroup_vote
• Add support for VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN.
• Support building MoltenVK for visionOS.
• Ensure non-dispatch compute commands don't interfere with compute encoding state used by dispatch commands.
• Support maximizing the concurrent executing compilation tasks via - MVKConfiguration::shouldMaximizeConcurrentCompilation
• Support VK_PRESENT_MODE_IMMEDIATE_KHR if VkPresentTimeGOOGLE::desiredPresentTime is zero.
• Add support for VK_PRESENT_MODE_IMMEDIATE_KHR to macOS Cube demo.
• Allow both renderPass and VkPipelineRenderingCreateInfo to be missing.
• Fix sync delay between calls to vkQueueSubmit() on non-Apple-Silicon devices.
• Ensure Xcode simulator always uses 256B buffer alignment.
• Don't attempt to force the window system to use the same high-power GPU as the app, on every swapchain creation.
• Log more info about SPIR-V to MSL conversion errors.
• Implement Deferred Host Operations.
• Support MSL Version 3.1.
• Drop official support for using Xcode 11 to build MoltenVK.
• To allow building MoltenVK without an internet connection, don't fetch a submodule if the commit is already known.
• Update dependency libraries to match Vulkan SDK 1.3.261.
• Update to latest SPIRV-Cross:
  • MSL: Fix argument buffer padding when content includes arrays.
  • MSL: ray-query intersection params
  • MSL: Support SPV_KHR_shader_ballot and SPV_KHR_subgroup_vote.
  • Skip line directives when emitting loop condition blocks.
  • MSL: Consider changed array types for array-of-constant-bool in struct.
  • MSL: Consider bool-short remapping for constant expressions as well.
  • Minor cleanup in constant_expression().
  • MSL: Add test for bool-in-struct edge cases.
  • MSL: Handle more complex array copy scenarios with bool <-> short.
  • MSL: Handle stores to struct bool[].
  • MSL: Consider bool/short remapping when dealing with composites.
  • MSL: fix function constant deduplication misfire

Marked as draft, since we need to wait for homebrew to update, and add their build to the CI.

This PR should allow for the removal of the various triangle fan workarounds on macOS.
