Raghunandan Bhat 3942681913 MDEV-35330: Assertion marked_for_read() failed in VSec9::VSec9 | Item_func_from_unixtime::get_date 
Problem:
  When a parameter in a prepared UPDATE statement uses DEFAULT value for
  a column (e.g., `EXECUTE IMMEDIATE 'UPDATE t SET b=?' USING DEFAULT`),
  and that column's default is derived from an expression or a function
  referencing another column (e.g., `FROM_UNIXTIME(a)`), the server fails
  to correctly mark the dependent column (`a`) for reading.

  This happened because the server failed to associate the `Item_param`
  (representing the `?` parameter) with its target field (`b`), leaving
  `Item_param::m_associated_field` uninitialized. This prevented the
  correct code path for evaluating the `DEFAULT` value, leading to the
  dependent column not being marked for read. When the column's value
  was later accessed, an assertion failed, causing a crash.

Fix:
  In the prepare stage of the UPDATE statement, associate each value
  with the target field, causing the server to take the correct code
  path (`Item_param::assign_default`) for evaluating DEFAULT values and
  marking dependent column for reading beforehand.
