Execution module function file.get_mode() should not exit with error if file not found

Description of Issue

I am using salt.file.get_mode() on a file that may not exist in a jinja function:

{% set current_mod = salt.file.get_mode("/tmp/file_that_does_not_exist") %}

When the file does not exist, I get a rendering error. I expect the function to return an error or None or something like that, not fail to render.

Likewise, doing the same operation from the CLI:

sudo salt-call --local file.get_mode /tmp/file_that_does_not_exist

exits with Salt failing. I would have expected that Salt successfully reported that the file does not exist, reporting None or False, etc.

Setup

I think above is sufficient, but will flesh them out if necessary.

Steps to Reproduce Issue

$ touch /tmp/file_that_does_not_exist
$ sudo salt-call --local file.get_mode /tmp/file_that_does_not_exist
local:
    0644
$ rm /tmp/file_that_does_not_exist
$ sudo salt-call --local file.get_mode /tmp/file_that_does_not_exist
Error running 'file.get_mode': Path not found: /tmp/file_that_does_not_exist
$ echo $?
1

Start by tracing the Salt execution-module entry point for file.get_mode(), then reproduce the missing-path behavior with the Jinja example and the salt-call command in the issue. Check the existing handling and tests for nonexistent paths; done means the function reports a nonfatal result such as None or False without causing rendering or CLI failure, with coverage for both uses.
