perf(core): use multiple directives in host bindings micro benchmark (#35736) 

This commit updates the host bindings micro benchmark to run tests with mutliple directives (where each directive contains host bindings). The number of directives is configurable as a constant in the micro benchmark file. This change is needed to have an ability to measure/compare perf in different scenarios.
