Add CMSIS RTOS2 wrapper (based on 2.3.0 API version).

[dmitrykos]

Also:

• Improve ISR compatibility for stk::sync classes.
• Improve performance of stk::sync classes.
• Modify GetTid() to return TID_ISR_N + ISR # value if called inside ISR (this allows stk::sync::Mutex usage inside ISR).
• Add stk::memory::BlockMemoryPool new API which is used for osMemoryPool API of CMSIS RTOS2 directly.
• Add sync::MessageQueue and sync::MessageQueueT<> wrapper.

Work in progress.
