Task list for VK_QCOM_tile_properties release

Allows applications to query the tile properties (tile size, apron size, and origin) of the implementation's tiling grid for both render passes (`vkGetFramebufferTilePropertiesQCOM`) and dynamic rendering (`vkGetDynamicRenderingTilePropertiesQCOM`). This information enables applications to optimize fragment density map creation, understand framebuffer-local dependency regions, and align render areas with tile boundaries for maximum tile rendering efficiency.

The task list for the VK_QCOM_tile_properties release is:

- [x] Vulkan Specification: https://docs.vulkan.org/refpages/latest/refpages/source/VK_QCOM_tile_properties.html
- [ ] Validation layer:
- https://github.com/KhronosGroup/Vulkan-ValidationLayers/pull/12531
- https://github.com/KhronosGroup/Vulkan-ValidationLayers/pull/12563

As each component is made public, the task will be checked off. When all tasks have been completed this issue will be closed and the extension will be fully released.

Start with the VK_QCOM_tile_properties specification page and review the linked Vulkan-ValidationLayers pull requests. The specification task is already checked; the release is done when the validation-layer work is public and the remaining task is checked off.
