Merge pull request #137 from jacobweinstock/build-arm64

Refactor multi arch builds:

## Description

<!--- Please describe what this PR is going to change -->
This is attempting to improve the time it takes to build both architectures and splits each image into its own GitHub actions job so that failures can be retried independently. 

## Why is this needed

<!--- Link to issue you have raised -->

Fixes: #

## How Has This Been Tested?
<!--- Please describe in detail how you tested your changes. -->
<!--- Include details of your testing environment, and the tests you ran to -->
<!--- see how your change affects other areas of the code, etc. -->


## How are existing users impacted? What migration steps/scripts do we need?

<!--- Fixes a bug, unblocks installation, removes a component of the stack etc -->
<!--- Requires a DB migration script, etc. -->


## Checklist:

I have:
