[TAS-257][TEST] add osnma benchmarking
* Introduced new benchmarks to assess the performance of various OSNMA related functions, such as public key verification. * Mostly recycled code from testing codebase. * TODO: methods are private, could not find a MACRO like FRIEND_TEST to allow for it. Result of this, only one benchmark test is active.
