The idea here is that these formed a major chunk of InstallRequirement's size
so, moving them and support code dedicated to them outside of that class
helps creates for better understandability for the rest of the code.
These are meant to be used elsewhere within pip to create instances of
InstallRequirement.

This does not check whether the target actually exists, only judge from the
appearance.
Returns true if any of the following conditions is true:
* a path separator is found (either os.path.sep or os.path.altsep);
* a dot is found (which represents the current directory).

First, it checks whether a provided path is an installable directory
(e.g. it has a setup.py). If it is, returns the path.
If false, check if the path is an archive file (such as a .whl).
The function checks if the path is a file. If false, if the path has
an @, it will treat it as a PEP 440 URL requirement and return the path.
