6d7ac9c9 - Support general session config entries in perf test tool (#19289)

Support general session config entries in perf test tool (#19289) ### Description Adds the ability to specify general session configuration entries via the `-C` command-line option. Example: `-C "session.disable_cpu_ep_fallback|1 ep.context_enable|1"` Some session config entries can already be set via dedicated command-line options. If the user uses multiple command-line options to set the same session config entry, we'll print a warning. Note that the dedicated command-line options will take precedence. ### Motivation and Context Allows setting session configurations when testing EPs. QNN EP, for example, uses the `session.disable_cpu_ep_fallback` and `ep.context_*` options.
