[Fix] (DirectVulkan): bound image mutability so Adreno keeps UBWC compression

- Every storage-capable colour texture was created MUTABLE_FORMAT, and Adreno
  gives up bandwidth compression on an image that may be viewed as any format in
  its compatibility class. MC's main render target therefore ran uncompressed;
  in a fill-bound scene that is the whole frame budget. Measured on Adreno 650,
  MC 26.2, same scene and camera, device cooled to 38-40C before each run:
  65.3 -> 80.9 fps (+23.9%), GPU busy ~93% in both.
- VK_KHR_image_format_list (enabled when present) fixes it without giving up
  mutability: VkImageFormatListCreateInfo names the exact formats a view may
  use, so the driver can keep the image compressed. The set must be exhaustive
  or the result is undefined - for sampled views it is exactly what
  ResolveSampledImageViewFormat can return over the three numeric domains.
- glBindImageTexture may name any compatible format, which cannot be enumerated
  ahead of time, so a texture bound to an image unit gets no format list. That
  is what VK_IMAGE_USAGE_STORAGE_BIT becoming on-demand is for: it makes
  "unmarked" mean "will never receive an arbitrary-format storage view", which
  is what makes the list sound. Removing STORAGE is worth nothing on its own
  (65.4 fps, measured) - only the mutability bound pays.
- MarkStorageImageTexture runs over every collected image-unit texture before
  the probe loop in PrepareStorageImageTextures, because that loop stops at the
  first texture needing work and would leave the rest unmarked. The mark makes
  NeedsStorageImagePreparation report true, which is what ends the render pass,
  so the recreate lands outside it.
- storageUsageResolved separates "not upgraded yet" from "this format can never
  carry STORAGE", so a format whose optimalTilingFeatures lack STORAGE_IMAGE
  cannot ask for a recreate that will never happen. SyncTexture's cross-draw
  early-out also has to break on a pending upgrade or the recreate never runs.
- An upgrade recreates the image and carries its contents forward through
  PreserveTextureContentsOnRecreate, which submits its own command buffer and
  waits. Whatever the frame already recorded into the old image is still
  unsubmitted, so that copy would read pre-frame content and this frame's
  rendering into the texture would be lost - exactly the render-target-then-
  image-unit case. PrepareStorageImageTextures now flushes first; it takes the
  FrameData rather than a command buffer because the flush retires the current
  one, and drops the sampled-descriptor-set memo that described it.
