Fix WGSL sign function to return correct int type instead of float (#7739)
* Initial plan
* Fix WGSL sign function to return int type properly
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Add vector version check for WGSL sign function test
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Fix FileCheck order in WGSL sign test - use DAG for order-independent checking
