CI: add on-demand address-sanitizer jobs

Description

• manual address sanitizer jobs for serial and MPI+OpenMP toolchains
• note: failing manual jobs do not result in a pipeline failure but instead show up as a warning
• adding this job does not require that it passes

Checklist

• I have checked that my code follows the Octopus coding standards
• I have added tests for all the new features added in this request.
