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.

All files in the project should have an empty line at the EOF. Necessary
for some pre-processing tools.

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

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.

Updates wsialloc and wsi::wayland::swapchain to support multiplane
image allocations.
Uses the custom allocator for allocations in Wayland image creation.

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.
