find elixir modules that require adding an alias

Basic code to find modules that require adding an alias. Sort of related to elixir-ls issue
Marking it draft due to some known test failures that I would like to get some suggestions on how to handle them.

Two of the tests fail as the newly added code suggests Kernel.SpecialForms as a new alias. I'm thinking this can be ignored from suggestions to fix.
One other test failure can be fixed by ignoring the suggestions from the new code(I've used this approach in some tests already, not sure if it's okay though)
I've updated code to be behind an opt

What do these numbers represent?

I think you could extract them to variables, just to get the magic-number look out of it:

Suggested change

	{line + 1, column - 10 + 2}
	line_offset = 1
	column_offset = -8
	{line + line_offset, column + column_offset}

@antedeguemon @lukaszsamson I've applied the suggestions and removed the usage of then due to failures for v 1.11.
