01a96ed37b The change makes the following adjustments:
* Changes the image state of ACQUIRED once the image has been presented as in shared present modes they are always in an acquired state.
* Removes thread free image semaphore signalling logic for shared present modes as there is only single image available and is always in an acquired state.
* Removes the reliance on the presentation thread for the shared present modes as it shouldn't be necessary for them as the headless mode does not share the buffer resource with any consumers.
* Adds the ability for swapchain_image class to not signal present fence for presentation request. On shared presentation modes we do not need to use the present fence and it cannot be used as the swapchain only has a single image.
* Adds support for present timing extension for shared present modes.
* When shared preset mode is used, the timings returned are always
* undefined as image is always in a state of being presented.

71a0881d5c This change updates the present timing implementation with several fixes and improvements for better spec compliance:
* Updated present timing logic and corrected macros to match Vulkan specification values.
* Added support for vkGetPhysicalDeviceCalibrateableTimeDomainsKHR to include stage-local time domains.
* Updated handling of VK_TIME_DOMAIN_DEVICE_KHR to return timestamps in nanoseconds.
* Modified vkGetPastPresentationTimingEXT to allow retrieval of records without requiring presentIds.
* Improved vkQueuePresentKHR to terminate early when the present timing queue is full.
* Fixed VkPastPresentationTimingEXT::presentStageCount to correctly report the number of stages containing definitive results.

ace729f7f8 Support nonzero present timing queue family
Adds a per-device check for a 'best' queue family to
use for present timing, rather than always using index 0.

wsi_ext_present_timing holds resources (such as the command
buffer) per queue family, rather than supporting only one. However,
currently, only one queue family is supported at a time.
In future, we can hook vkGetDeviceQueue calls to map
VkQueues to their family index. Doing this will transparently
give present timing support for multiple queue families.

dfe88e3c1c The patch changes the following:
* Implement scheduling support for headless present stages.
* Fix a bug where present query stages were added to the internal queue when application did not request any.
* Change the implementation of present timing extension to store device_private_data rather than VkDevice as all queries require it.
* Document the shortcomings of implenting scheduling support for Wayland backends.

c43dd058ed Implement monotonic stage timestamps on headless
Sets timestamps for `vkGetPastPresentationTimingEXT` for the remaining
present stages on headless:

- VK_PRESENT_STAGE_IMAGE_LATCHED_BIT_EXT
- VK_PRESENT_STAGE_IMAGE_FIRST_PIXEL_OUT_BIT_EXT
- VK_PRESENT_STAGE_IMAGE_FIRST_PIXEL_VISIBLE_BIT_EXT

These are all set to the same value: when swapchain::present_image is
called. It uses the best monotonic clock supported by the driver.

No need for slot member variables to be atomic any more because they
are only accessed while a lock on m_queue_mutex is held.

a92fa2a8d9 Add support for querying swapchain timing properties
Adds initial support to the headless and Wayland backends to query
swapchain timing properties. This patch also moves all present timing
backend specific code into its own file and refactors the private_data
code that is specific to present timing entrypoints into a more common
format.
