Adding ARM build on self-hosted images (#605)

## Description

This change added the SBSA builds on self-hosted ARM systems. This work
was left out because we need a change from BaseTools to resolve a build
break when using native ARM gcc compiler, which we have now in 202302
mu_basecore.

This change resolves
microsoft/mu_basecore#369.
