In older version of MATLAB, automatic tab completion can be configured through editing TC.xml located in \matlabroot\toolbox\local\. In MATLAB 2016, however, this file no longer exists. How I can configure tab completion for my own function in MATLAB 2016 then ?

As it turns out, MATLAB 2016 uses a functionSignatures.json file to configure automatic tab completion. One can easily read the content of any such file you find within the $matlabroot\toolbox\ folder to understand how it works.
Here is a very simple example functionSignatures.json file showing how to set up tab completion for a function named nd2finfo :
{
"nd2finfo":
{
"inputs":
[
{"name":"nd2file", "kind":"required", "type":"filepath=*.nd2" }
]
}
}
This file should be saved within the same folder that has the function definition. While typing in the function input, upon pressing tab, I can see a list of files with the extension .nd2 popping up.

Note that, as of R2018a, this capability is documented and supported. See Customize Code Suggestions and Completions
