b02486ff87 Extend wsialloc_alloc with disjoint information
Extends wsialloc_alloc to return whether or not the allocation will be
disjoint.

Groups wsialloc_alloc's return values to a struct.

2bc2109194 Add support for VK_EXT_image_compression_control_swapchain
Implement support for VK_EXT_image_compression_control_swapchain
for both the Wayland and the headless windowing systems.
The extension can be conditionally enabled through the new build option
BUILD_WSI_IMAGE_COMPRESSION_CONTROL_SWAPCHAIN. Compiling with this
option enabled requires recent Vulkan headers (1.3.213)
Note also that support in the layer is enabled conditionally to
the ICD supporting VK_EXT_image_compression_control.

Update the WSIALLOC interface to version 2 and add support to
prefer selection of a format with the highest fixed rate compression
from the formats provided. This is used to pick a fixed rate
compression when VK_IMAGE_COMPRESSION_FIXED_RATE_EXPLICIT_EXT is
specified during swapchain creation.

1701c1fea4 Add versioning to wsialloc interface
The wsialloc interface now has explicit versioning which is used to
ensure that wsialloc implementations are compatible with the interface.
wsialloc implementations should define which version they are using and
upon version mismatch compilation will fail.

Also:
- add new WSIALLOC_MAX_PLANE macro to define the maximum number of
planes that the wsialloc should support.

293ae2ab13 Implement a vendor agnostic wsialloc interface
Refactors the wsialloc interface in the layer.
This patch ensures that wsialloc interface could be ported
to different GPU architectures and systems that could
have different requirements

241e05d3e4 Resolve segfault in wsialloc_delete
A segfault can occur if wsialloc_delete is called but m_wsi_allocator's
ion field has not been allocated yet, as the function attempts to access
the ion properties.

This commit resolves the issue by changing m_wsi_allocator to an opaque
struct and removing the fd property, which was not being used.
wsialloc_new is then changed to return a pointer to the struct and
the swapchain then carries this pointer around, which will be
initialised to nullptr in the swapchain constructor.

8dc4d923ff Adds initial support for VK_KHR_wayland_surface.
Very basic Wayland support is implemented by importing
memory with VK_EXT_image_drm_format_modifiers.
The current implementation requires an external system
memory allocator. An API for this allocator is defined
in util/wsialloc/wsialloc.h and an implementation using
the ION memory allocator is included.

Outstanding issues:
 * This is an initial prototype for Wayland support and
   has many outstanding TODOs which need addressing to
   properly use the Wayland protocol.
 * Using ICD Exported memory instead of a system allocator
   is not implemented.

Wayland support is still experimental and outstanding issues
will be fixed in future commits.
