[AMF,SMF,PCF] Rename the function for calculating NF Instance load

- have a more consistent naming among the NF's
- always have the same prefix (amf_/smf_/pcf_) depending on the NF
- function name is always the same, how the function calculates the load
is NF specific and internal to the function itself (but not the function
name).
