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.

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.
