Please add ARM64 (aarch64) compiled packages to repositories

#### Description

When creating new images for RHEL Clone (EuroLinux) on ARM64, I discovered that there is no Packer for aarch64 as RPM is available.

**I get that there is standalone binary download, but RPM is easier to manage, update etc.**

#### Use Case(s)

Creating:

- AWS base images
- Creating Libvirt/KVM Vagrant Boxes
- Creating images for Mac M1

#### Potential configuration

[According to packer documentation](https://www.packer.io/downloads)
```
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo
sudo yum -y install packer
```
Currently, there are the following packages:
```
[root@localhost yum.repos.d]# dnf --disablerepo="*" --enablerepo="hashicorp" list available
