Miscellaneous build and documentation updates.

- Disable Mac Catalyst builds from all and all-debug in Makefile,
  due to unresolved issues with Mac Catalyst builds.
- Disable numerous deprecation warnings in visionos builds.
- Remove references to deprecated MTLFeatureSet.
- Remove MVK_CONFIG_SUPPORT_LARGE_QUERY_POOLS from
  MoltenVK_Configuration_Parameters.md document.
- Update Whats_New.md document.

-#### MVK_CONFIG_SUPPORT_LARGE_QUERY_POOLS

-##### Type: Boolean
-##### Default: `1`
-
-Depending on the GPU, _Metal_ allows 8,192 or 32,768 occlusion queries per `MTLBuffer`.
-If enabled, **MoltenVK** allocates a `MTLBuffer` for each query pool, allowing each query
-pool to support that permitted number of queries. This may slow performance or cause
-unexpected behaviour if the query pool is not established prior to a _Metal_ renderpass,
-or if the query pool is changed within a renderpass. If disabled, one `MTLBuffer` will
-be shared by all query pools, which improves performance, but limits the total device
-queries to the permitted number.

-- .
+- Improved occlusion query support:
-- New state tracker implementation.
+  - Add support for occlusion queries across multiple renderpasses.
-- New descriptor set/pool implementation.
+  - Improve performance by accumulating occlusion quieries in parallel, 
-	- The new implementation is less forgiving of applications that don't properly manage the lifetime of their descriptors
+    and using untracked buffers to avoid encoder serialization.
-	  (and bind them after the objects they point to have been destroyed).
+- New descriptor state tracker implementation to improve performance.
-	  Use `MVK_CONFIG_LIVE_CHECK_ALL_RESOURCES=1` to revert any crashes this might cause, or mark potentially-destroyed descriptors

+- Added working demo target for VisionOS in Cube Demo.
+- Raise minimum target to _macOS 11.0 / iOS 14.0 / tvOS 14.0_
+- Add support for `VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT`.
+- Reject image usages whose format features are not supported.
+- Return `VK_ERROR_OUT_OF_POOL_MEMORY` when running out of descriptor sets.
+- Make vkGetPhysicalDeviceToolProperties() an instance function.
+- Enable sample LOD bias for Xcode 26.
+- Fix VkExternalMemory*CreateInfo not allowing host memory handle types.
+- Fix improper boundary error when requesting exactly the number of variable descriptors allocated.
+- Fix regression on functions used by multiple extensions.
+- Fix improper use of dynamic depth/stencil attachment.
+- Fix out-of-bound access when using multiview with multiple subpasses.
+- Deprecate configuration parameter `MVKConfiguration::supportLargeQueryPools` and corresponding environment variable 
+  `MVK_CONFIG_SUPPORT_LARGE_QUERY_POOLS`, as obsolete and ignored. Large query pools are now supported always.
+- Disable Mac Catalyst builds from `all` and `all-debug` in `Makefile`, due to unresolved issues with Mac Catalyst builds.
