Basic ARM builds

[jae1911]

This PR adds:

• Basic ARM builds for the library

Modifies:

• Merges the two workflows into a single file that handles publishing

The current workaround uses Qemu and Docker to build the binary for ARM as runners for this platform aren't available yet. This configuration will be easy to convert to native ARM instructions when the runners are finally available publicly.

libFreeImage.so: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, BuildID[sha1]=0381ef64436c174f64d87a4a15e0032548fa06f0, stripped

This works now.

It takes a long time, but it works.
