  -----------
  [clang] Fix assertion crash in alloc_size structural equivalence check (#199407) (#199980)

Fixes #199407

Remove ParamIdx from the `USE_DEFAULT_EQUALITY` default-comparison path
and add an explicit `equalAttrArgs<ParamIdx>` specialization that safely
handles invalid (unset) values.
