Agent Profiling Fixes for Broken/Improper API Usage (#1122)

Prevent's multiple setups of agent profiling on the same agent.

Fixes agent read context to only read agents that were setup.

Prevent copy of agent profiling internal data struct and reset
hsa_signal on move to prevent inadvertant delete.
