Melissa Elkadi 4dd579e042 int32_t to c16_t conversion 
This commit includes changes to the function
footprints for vaiours NR UE and gNB functions.
It does not updated the LTE code. For functions
shared by both LTE and 5G, we maintained the original
LTE footprint and argument structure.

Several of the simulators that use these functions
have been updated as well. The specific usage of these
functions which index into the int32_t buffers and
treat the first int16_t and the real and the second
as the complex should be modified in the near future.
