mesh: Add new kernel MGMT based IO transport

1. Re-structures MGMT handling such that it is used to detect kernel
   support of the mesh MGMT opcodes and events before selecting between
   using MGMT or the legacy raw HCI socket method.

2. Re-structures main() to allow command line to prefer MGMT over HCI or
   visa versa, plus optionally pass an explicte controller.

3. Adds mesh-io-mgmt as a transport.
