Subject: [PATCH] refactor: Refactor function `_glfw_calloc`

A simple refactor for the `_glfw_calloc` function. It does not modify the original function behavior, it just makes it more human readable and reduces the indentation.

Also, I created a constant called `total_size`, so the program doesn't need to multiply the same two variables three times.
