tests: settings: Performance test for settings
This adds a on target performance test for Settings SS. Using this test performance of the Setting SS + NVS/ZMS backend can be benchmarked. The test repeatedly write 128 settings entries. Each setting entry has a size of 4 bytes, and path length of 16 bytes (excluding the null-terminator). The test has two variants, with and without Bluetooth scan running. This is useful to benchmark performance along with some component of BT subsystem activated. The test could be enhanced in future to include or create combinations of different functionalities running, when agreesive store operations are happening.
