One: Compiler FE: conversion of pytorch to TF with Ops

[seanshpark]

As next step of #4795, let's check our list of Ops.

@underflow101 , I've done with my first target of operators in my list.
If you like, you can add other operators that converts to tflite with ptem.py
And it is OK to add that don't convert to tflite with a Note like #4898 or #4900

Thank you, @seanshpark ,
I will add more PyTorch examples. And thank you for your prior examples! :)
I will take a look in #4898 or #4900 which doesn't convert to tflite.

Done :)
