Include fedora and centos os matrix for ARM cluster (RedHatQE#2430)

Updated config file to include fedora and centos os matrix for ARM
cluster

##### Short description:
ARM config file lacks information for fedora and centos os matrix.
Earlier, ARM tests ran good as some of the tests were using cirros. Now
few tests uses fedora and centos images, and the test fails with missing
fedora & centos os matrix. So this PR adds those os matrix to the config
file

##### More details:
This PR adds Fedora/Centos OS matrix for ARM cluster env. Without this
fix, test run fails.

##### What this PR does / why we need it:

##### Which issue(s) this PR fixes:

##### Special notes for reviewer:

##### jira-ticket:

## Summary by CodeRabbit

* **New Features**
* Added Fedora and CentOS OS matrices for ARM64 and updated selection to
expose latest entries for multiple OS families.
  * Removed legacy CentOS-specific instance-type matrix.

* **Chores**
* Standardized disk and QCOW2 image names across architectures with new
shared constants.
* Reworked ARM64 and s390x image configurations to use standardized
names, derived Cirros filenames, and explicit latest-release references.
