Use safe_numel() in et

[lucylq]

Stack from ghstack (oldest at bottom):

• ->Use safe_numel() in et #19075
• Add safe_numel() #19074

The wasm bindings' assert_valid_numel() helper previously computed numel without overflow detection, letting a malicious tensor shape wrap to a small value that bypassed the data-size check. Replace with safe_numel() (returns Result<ssize_t>) and propagate the error via THROW_IF_ERROR as a JavaScript exception, matching the rest of the wasm error plumbing.
