Fix backdrop-filter with invalid mask image issue

According to https://drafts.fxtf.org/css-masking-1/#the-mask-image, an
invalid mask image should generate a transparent black mask layer that
hides the content. However, when backdrop-filter is used with invalid
mask images, the content is still created and rendered.

This change adds AllImagesAreInvalid() checking in
PaintPropertyTreeBuilder for elements with backdrop-filter. When an
element has both mask-image and backdrop-filter specified, but all mask
images are invalid (failed loads, invalid URLs, slow-loading, etc.),
PaintPropertyTreeBuilder directly checks this condition and sets
opacity=0, correctly hiding the element and its backdrop-filter as
required by the spec for invalid mask images.

The fix is guarded by the HandleInvalidMaskImageWithBackdropFilter
runtime feature flag as a killswitch.

WebNN: Replace null characters in node names for ORT backend

Operation label contains null characters ('\0') may cause ORT's
CreateSessionFromModel API to fail with "two nodes with the same node
name".

This CL adds a WPT case introduces a graph containing two add operations
named 'node\0a' and 'node\0b'. These will be truncated to the same name
'node' in the CreateSessionFromModel API and leading to the error.

This CL replaces all '\0' characters with '_' in operation labels to
ensure compatibility with ORT's C API. And the unique
next_operation_id_ appended to node names prevented collisions.

Recompute intersection observations on z-index changes

Intersection observations are recomputed when paint is invalidated (see
PaintInvalidator::InvalidatePaint), but z-index changes do not always
invalidate paint, so we need to ensure intersection observations are
recomputed in those cases.
