[Python] Mark "X" in from ___ import ___ as X as a "Definition"

from module import thing as alias

alias('foo')
alias('bar')

Hovering over alias on one of the bottom lines will show a popup with a "References" section that links to the other bottom one.

Expected behavior

It'd be great if there was also a "Definitions" section in the popup that linked to the alias on the first line. Ideally, it would be a definition for the one file. (i.e. alias in other files would not find it.)

If I hadn't given thing an alias, uses of thing would be linked to the thing definition in module.py, but there isn't any definition for alias apart from the import as.

Actual behavior

Understandably, there is no Definitions section currently in the popup.

Depends on #1842.

The question here is how to distinguish module imports from functions etc.

thing could be anything - a module, function, variable. Don't think it's useful to just scope it entity.name without being able to properly link it with references.
