Fixing merge issues for #2901 "Average function"

[LeumasA]

A follow up on the previous merge request for the average function. I noticed that the layout of the ivy repository was changed and the original functions file for the tensorflow frontend was replaced a "layers" file instead. I've added the function to that new file and hopefully this should fix the merge conflicts. Any other problems let me know.

@LeumasA Hello, it seems like you are writing code from the little previous version.

You should update the code to the latest Ivy version. Additionally, the average function needs to receive two arguments x, and y. The current implementation just receives x alone.

Just ignore the function which was moved to another file and modify the average function!

Thank you
