fuchsia: Create mutable-format sysmem external images.
If we create an image importing VMOs from BufferCollection, the formats
used in clients may be slightly different (e.g. R8G8B8A8_UNORM in
Flutter vs. R8G8B8A8_SRGB in Scenic), which caused graphical artifacts
on some platforms.
This change enforces all sysmem-backed images use flag
VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT to explicitly support multiple
formats.
