## Description

This extension adds the VkQueryLowLatencySupportNV structure, a structure used to query support for NVIDIA Reflex.

## New Structures

- Extending VkSemaphoreCreateInfo:

  - VkQueryLowLatencySupportNV

## New Enum Constants

- `VK_NV_LOW_LATENCY_EXTENSION_NAME`

- `VK_NV_LOW_LATENCY_SPEC_VERSION`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_QUERY_LOW_LATENCY_SUPPORT_NV`

## Issues

1) Why does `VkQueryLowLatencySupportNV` have output parameters in an input chain?

RESOLVED: We are stuck with this for legacy reasons - we are aware this is bad behavior and this should not be used as a precedent for future extensions.
