PS-10065 feature: Integrate 8.4 testing into the CI (#63)

https://perconadev.atlassian.net/browse/PS-10065

GitHub Workflow Actions now perform MTR testing not only with MySQL Server 8.0 but
with 8.4 as well.

Changed the way how MySQL Server is installed on the system: instead of relying on the
system packages we now download tarballs directly from the Oracle web site:
* linux-glibc2.28-x86_64 for 8.0
* linux-glibc2.28-x86_64-minimal for 8.4

Removed apparmor invocation  / package installation.

Added manual "libaio.so.1" symlink creation (required by MySQL Server tarball binaries).
