Add a buffer shader variant for native_layer_norm using workgroup-based
reduction with shared memory. Each workgroup handles one output row, with
NUM_WORKERS (64) threads cooperatively reducing across the row width for
mean and variance computation. Rename the existing texture shader to
native_layer_norm_texture.glsl/.yaml and register the op as ANY_STORAGE
so buffer-storage inputs are now accepted.
