Add rocprofiler_load_counter_definition (#1193)

Adds rocprofiler_load_counter_definition. This function allows a counter definition file to be supplied to rocprofiler-sdk directly. Takes in a string containing the counter definition YAML, its size (in bytes), and a flag value to state whether this is an append operation or not.
