  Revert "Vulkan: Simplify/Fix DmaBufImageSiblingVkLinux import probing"
  
  This reverts commit d917f77130e5194e82418f3bdaa2cd5b2af55c03.
  
  Reason for revert: Google Meet Regression https://crbug.com/445863166
  
  Original change's description:
  > Vulkan: Simplify/Fix DmaBufImageSiblingVkLinux import probing
  >
  > Remove the multi-format probing logic in DmaBufImageSiblingVkLinux.
  > Use the renderer’s base VkFormat and a single check with
  > VkImageFormatListCreateInfo, instead of looping over mVkFormats with
  > mutable/non-mutable combinations. This cuts down redundant queries
  > and streamlines initImpl.
  >
  > Also, this CL fixes some issues occur when mapping DRM format into
  > Vulkan backend formats.
  > - Default to SampleOnly but prefer Renderable if the modifier properties
  > exposes both sampling and rendering, since usage at import time is
  > unknown.
  > - Fix emulated-format handling issue by using getIntendedFormatID() and
  > getActualImageFormatID() instead of deriving both IDs from VkFormat with
  > GetFormatIDFromVkFormat() directly.
