  Log Message:
  -----------
  [webkit.UncountedLambdaCapturesChecker] Fix a bug that the checker didn't take the object pointer into account. (#125662)

When a callee is a method call (e.g. calling a lambda), we need to skip
the object pointer to match the parameter list with the call arguments.
This manifests as a bug that the checker erroneously generate a warning
for a lambda capture (L1) which is passed to a no-escape argument of
another lambda (L2).
