Shintaro Kawamura ca6adae33c crosvm_control: add swap status/trim command support
SwapStatus, SwapState, SwapStateTransition, SwapMetrics are directly
contained into crosvm_control.h

SwapState is translated as C++ enum.

SwapStateTransition::time_ms is now u64 because u128 does not support
repr(C).

Changed usize in the structs to u64 because usize is translated as
uintptr_t.

BUG=b:265386761
TEST=cargo build -p crosvm_control
