In the table of https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/wikis/Potential-Duplicates, there are listed some functions that differ only by the `*_ivas_fx` appendix. In fact, these functions are different in terms of accepting different data-types (Word16 vs. Word32) of input buffers/parameters. These functions are usually differentiated in the framework by the appendix `*_fx()` vs. `*_fx_32()`. This MR proposes to follow this logic for the functions listed at https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/wikis/Potential-Duplicates. <!--- Below are labels that will be added but are not shown in description. This is a template to help fill them. Add further information to the first row and remove and add labels as necessary.-->
