Oleksandr Gabrylchuk 02fab4cf9e venus: Implement guest vram blob type. 
Add support of GUEST_VRAM type of blob. These are dedicated heap memory
allocations required for vk support on hypervisors that don't support
runtime injections of host memory into guest physical address space.

The flow of usage:
1) Host VM reserves dedicated heap memory
2) Device get info about memory reservations and report it to guest
using mmio registers
3) Guest virtio-gpu driver on starts checks mmio registers for
physical address and length of reserved region. Then it reserves it
in guest.
4) On each call of vkAllocateMemory() guest driver gets chunk of
required memory and send it to host using sg list. It uses one sg
entry for 1 blob call. Heap is managed on guest using drm memory
manager (drm_mm).

Chia-I Wu 9c81de7df2 venus: cache shmems 
Shmems are allocated internally and are only for CPU access.  They can
be easily cached.

Venus have 4 sources of shmem allocations

 - the ring buffer
 - the reply stream
 - the indirection submission upload cs
 - one cs for each vn_command_buffer

The first one is allocated only once.  The other three reallocate
occasionally.  The frequencies depend on the workloads.

Yiwei Zhang ccefcb0baf venus: fix misaligned bo_flags between import and query 
For importing an dma_buf fd, export info is not required. Leaving the
bo_flags missing VIRTGPU_BLOB_FLAG_USE_SHAREABLE bit as well as the
VIRTGPU_BLOB_FLAG_USE_CROSS_DEVICE bit. Upon querying fd properties,
DMA_BUF handle type will be specified which generates a new bo_flags
not matching the prior one.

This patch aligns the above 2 bits for the dma_buf import path.

Test: vkGetAndroidHardwareBufferPropertiesANDROID should succeed with
      a valid AHB with AHARDWAREBUFFER_FORMAT_BLOB format.

This is because virtgpu::fd is zero-initialized upon allocation, which causes fd 0 to be closed in virtgpu_destroy.

Chia-I Wu 40fbfd8b5b venus: fix dmabuf import mmap_size check 
Do not set mmap_size to info.size.  We do not track the size of the BO
anymore.

This fixes
dEQP-VK.api.external.memory.dma_buf.suballocated.device_only.fd_properties
where the test allocates a 1KB VkDeviceMemory, export and call
vkGetMemoryFdPropertiesKHR.  It can happen that bo->mmap_size is less
than the aligned info.size.

FWIW, the test fails because it violates a VU:

  VUID-vkGetMemoryFdPropertiesKHR-fd-00673
  fd must be an external memory handle created outside of the Vulkan API
