[flang][OpenMP] TODO in atomic capture for different yet compatible types

[NimishMishra]

The PR #131603 introduces a TODO for atomic capture for different yet compatible types. Such scenarios require implicit type casting, and end up emitting > 3 operations in the atomic capture region:

program main
   integer :: x
   real :: y

   !$omp atomic capture
        y = x
        x = x + 1
   !$omp end atomic
end program main

The above test produces the following TODO: not yet implemented: atomic capture requiring implicit type casts
