  Log Message:
  -----------
  [flang][cuda] Lower c_devptr value arguments in bind(c) like c_ptr (#199316)

Treat `type(c_devptr), value` arguments in BIND(C) interfaces like
`type(c_ptr), value` by passing the nested raw address value instead of
the outer derived type ABI. This keeps call signatures consistent for
CUDA Fortran generic specifics that share a C binding label and avoids
argument misclassification at the x86_64 register/stack boundary.
