Zink sets multiple external memory handle types(like Opaque FD,DMA-BUF)
without confirming if the Vulkan driver actually supports them. This may lead
to failures when attempting to allocate external memory with vkAllocateMemory.
This patch introduces query_external_memory_compatibility() to verify
handle type support via VkPhysicalDeviceImageFormatProperties2.
Combine handle types only if they are compatible; otherwise, use a single
supported type as a fallback.

find_good_mod was accumulating DISJOINT_BIT across iterations and
setting ici->usage on success. Change it to return results via
out-parameters and save/restore ici->flags around each modifier
attempt. The caller (negotiate_image_config) now explicitly sets
ici->usage and ici->flags after find_good_mod returns.
Also save/restore flags in the LINEAR modifier fallback path.

Replace the nested retry loops (eval_ici, set_image_usage,
double_check_ici, suboptimal_check_ici, try_set_image_usage_or_EXTENDED)
with a flat candidate array that encodes the same fallback order.
Instead of mutating a shared VkImageCreateInfo through deeply nested
function calls and retrying with toggled flags, we now:
1. build_usage_candidates() generates an array of (tiling, usage,
flags, has_format_list) tuples in preference order
2. try_image_config() applies each candidate and calls check_ici
3. negotiate_image_config() iterates tiling/extended combos, builds
candidates for each, and takes the first passing one
The modifier path (find_good_mod) is kept separate since it iterates
modifiers and takes the last good one (max-by-position, matching
the GBM worst-to-best convention), which is fundamentally different
from the candidate model's first-match-from-fallback-chain.
Duplicate candidates from the old code's redundant retry paths are
eliminated via dedup_configs(). The pNext chain surgery in
double_check_ici (manually unlinking VkImageFormatListCreateInfo) is
replaced by try_image_config's explicit format list chain/unchain.
The cube-compatible post-pass is simplified to a single check_ici
call instead of re-running the full negotiation.
