Merge 7c1ec4a59e into fce0398470

When a module uses torch.nn.utils.parametrizations.weight_norm, its weight
parameter is moved into a 'parametrizations' child sub-module as original0/original1.
named_parameters(recurse=True) yields 'parametrizations.weight.original0' while
named_parameters(recurse=False) does not, causing _load_list() to incorrectly
classify the module as having random weights in non-leaf sub-modules and skipping
it during partial VRAM loading.

The fix skips 'parametrizations.*' entries in the check, so weight-normed modules
are correctly included in the load list and their parameters moved to GPU as needed.

The AudioOobleckVAE (Stable Audio) had a disable_offload=True workaround that
forced full GPU load to avoid this bug. With the root cause fixed, that workaround
is no longer necessary and is removed, allowing partial VRAM offloading on systems
with limited GPU memory.

Fixes #11855
