Kunal Dubey 2c6332a7d6 fix: resolve getFileHandle concurrent stalling by queuing callbacks (#50597)
Previously, concurrent calls to FileSystemAccessPermissionContext::ConfirmSensitiveEntryAccess
for the same file path would silently discard the subsequent callbacks because
the internal callback map used a single callback per file path and std::map::try_emplace
would drop the callback if the key already existed. This caused Promises in JS
(e.g., dirHandle.getFileHandle()) to stall indefinitely.

This commit updates the callback map to hold a vector of callbacks, so all
concurrent requesters for the same filepath are grouped together and resolved
once the asynchronous blocklist check completes.

Notes: Fixed an issue where concurrent `getFileHandle` requests on the same path could stall indefinitely.
