AK: Add volatile overloads to AK_ENUM_BITWISE_OPERATORS

Browse Source 
These overloads return void, since GCC otherwise complains if you
ignore the return value:

implicit dereference will not access object of type
'volatile Kernel::PCI::Registers::Control' in statement [-Werror]
  132 |     registers->control |= Registers::Control::PERST_N;
