Stack-use-after-scope in Grid async decoding
Description
Decoding a crafted HEIF grid image triggers stack-use-after-scope at libheif/image-items/grid.cc:498. The lambda passed to std::async captures a reference to the destroyed stack variable progress_counter, leading to info-leak or potential DoS.
