hwl: Fixes seldom compile error and move semantics for bus variables

Fixes some bugs in the hardware layer module

Bug Fixes

• [hwl]:
  • Fixed noexcept signature of defaulted copy constructor: this caused problems for some compiler versions
  • Fixes bus variable move constructor. When moved, a new mutex is used. The alternative is wrapping the mutex in a unique_ptr, which reduces cache-coherency though.
  • Fixes variable base class constructor calls for mutex/lock class types changed via macros

Breaking Changes

• [hwl]:
  • makeDevice() API changes to not adding the device to the bus yet. (old variant wouldn't have worked anyway)
