Fortran: Move pointer nullification code to new function

Fortran compiler extracts pointer nullification logic into a dedicated function for better code organization.

The Fortran compiler has consolidated the code responsible for nullifying pointers into its own function. This refactoring improves code organization within the compiler’s intermediate representation translation, making the pointer assignment handling clearer.

In Details

The Fortran frontend introduces gfc_nullify_descriptor in trans-descriptor.cc to encapsulate the pointer nullification logic previously found in gfc_trans_pointer_assignment. This function handles setting the descriptor's data pointer to null.

For Context
array descriptor
A data structure used by the Fortran compiler to represent arrays, holding information such as data pointer, type, rank, and bounds.
pointer nullification
In Fortran, the process of setting a pointer to the 'null' state, indicating it does not currently point to any memory location.
trans-descriptor.cc
A GCC source file containing functions for creating and manipulating array descriptors during the intermediate representation (IR) translation phase.
