WebGPURenderer: Workgroup Arrays and Barrier Support (#29192)

* init * barrier, private array, workgroup array support * clean * Implement Renaud suggestions * fix * fix storage buffer example with workgroupBarrier() * add tags and other info * add bitonic sort example * update * Rebase branch * try to fix bitonic sort shader * simplify * fix * bitonic sort now works but local swap is slower than global swap : * cleanup * fix rebase issues * Change display and html to make difference between global and local swap clearer. May want to improve the performance of the fragment shader by writing nextAlgo and nextBlockHeight to uniforms on the CPU side * update (ugly?) screenshot * cleanup ---------
