Add test results visualization

[mw-kapilg]

This feature creates an in-platform view for MATLAB test results (whenever a default test runner or pre-made TestTask is used) if the user has a MATLAB Test license.

Key highlights:

• Each row of the table represents the test file.
• All tests for a single file are shown under that file.
• The files with same name and different parent directories are shown separately and you can hover over the file name to see its path.
• The table in table format allows easy management of test cases for a test file
• You see the logs in-place for a failed/incomplete. If there are more than failures within a test case, say multiple verification failures, each verification failure will have its own dropdown and log box.
• Each of the passed, failed, etc. buttons act as filters to respective type of tests
• The "Open in MATLAB Online" button helps to redirect users to MATLAB Online. If their Jenkins project is connected to a git repository, they are prompted to open the in MATLAB Online for easy debugging.
• The help button redirects users to our plugin's configuration guide.

Here's a few snapshots:
