Roman Stratiienko 22809765ac v3dv/android: Enable shared presentable image support 
Functionality ensures gralloc won't allocate compressed buffer
incompatible with shared presentable image support.

Broadcom does not support compressed buffers and we can just enable the
feature without additional logic. Despite that, we add the logic here
so it can be replaced with the generic code someday.

/* For the full details on loader interface versioning, see
* <https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/blob/master/loader/LoaderAndLayerInterface.md>.
* What follows is a condensed summary, to help you navigate the large and
* confusing official doc.
*
* - Loader interface v0 is incompatible with later versions. We don't
* support it.
*
* - In loader interface v1:
* - The first ICD entrypoint called by the loader is
* vk_icdGetInstanceProcAddr(). The ICD must statically expose this
* entrypoint.
* - The ICD must statically expose no other Vulkan symbol unless it is
* linked with -Bsymbolic.
* - Each dispatchable Vulkan handle created by the ICD must be
* a pointer to a struct whose first member is VK_LOADER_DATA. The
* ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
* - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
* vkDestroySurfaceKHR(). The ICD must be capable of working with
* such loader-managed surfaces.
*
* - Loader interface v2 differs from v1 in:
* - The first ICD entrypoint called by the loader is
* vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
* statically expose this entrypoint.
*
* - Loader interface v3 differs from v2 in:
* - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
* vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
* because the loader no longer does so.
*
* - Loader interface v4 differs from v3 in:
* - The ICD must implement vk_icdGetPhysicalDeviceProcAddr().
*
* - Loader interface v5 differs from v4 in:
* - The ICD must support Vulkan API version 1.1 and must not return
* VK_ERROR_INCOMPATIBLE_DRIVER from vkCreateInstance() unless a
* Vulkan Loader with interface v4 or smaller is being used and the
* application provides an API version that is greater than 1.0.
