kernel/physical_core: Make use of std::unique_ptr

shared_ptr was used in 8eb175481c due to a
misunderstanding of how the language generates move constructors and
move assignment operators.

If a destructor is user-provided, then the compiler won't generate the
move constructor and move assignment operators by default--they must be
explicitly opted into.

The reason for the compilation errors is due to the fact that the
language will fall back to attempting to use the copy constructor/copy
assignment operators if the respective move constructor or move
assignment operator is unavailable.

Given that we explicitly opt into them now, the the move constructor and
move assignment operators will be generated as expected.
