Subject: [PATCH] Self hosted runners (#898)

Description of the problem
Our Debug CI using Github Actions is very slow (taking over 4 hours and a half to complete).

Description of the solution
I have deployed two local machines here to become our DEBUG CI. They take around 50 minutes to complete everything, which is a significant improvement.

How Has This Been Tested?
Ran them for a day and it seems everything is still good.

Comments
-More machines will be added in the following weeks. Hoping to reach like 5.
