arm-auto-solutions/oeqa: Add test for Platform Fault Detection Interface

Add OEQA runtime test to validate Platform Fault Detection
Interface(PFDI) functionality.

The test executes the PFDI application workflow by generating test
configurations, packing them running the generated binary and
validating the results for online PFDI execution.

The test also adds a validation method to validate 'pfdi-cli'
commands with error injection
