{Core} Ignore psutil.AccessDenied in _get_parent_proc_name

Description

Fix #19193

When parent or grandparent process path is too long, psutil used by Azure CLI fails:

Traceback (most recent call last):

psutil.AccessDenied: psutil.AccessDenied (pid=1080)

The psutil issue is tracked at giampaolo/psutil#1980

Change

This PR ignores psutil.AccessDenied so that get_parent_proc_name won't fail.

Testing Guide

Use legacy Windows PowerShell terminal powershell.exe to launch Azure CLI with a very long path:

D:\cli\py38-32\Scripts\pythonloooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong.exe -m azure.cli --version --debug

• After this PR, get_parent_proc_name won't fail as we ignore psutil.AccessDenied
• In addition, if CLI is run in a no-TTY environment, like ADO, color will be disabled automatically and get_parent_proc_name won't be called at all.
