Add IPMI OEM command LinuxBootDone

Add a new OEM command for LinuxBoot to notify the BMC when it is about
to kexec into the OS. This is intended to give the BMC a chance to
prepare for an untrusted OS, e.g. disable any interfaces it doesn't want
the OS to have access to.

This will read a json config and return the bifurcation based on that.
It will read the configure file in a persistent file to see if it is
valid machine config and return the bifurcation information

For example,
If it is valid config, it will return 8x8 for PE1,3,4,6.

google-ipmi-sys: Refactor to use new version of OEM IPMI Handler

Using the new version of ipmi handler provide a higher level wrapper
over the same functionalities. It helps us parse the input and output to
have more control of the input/output we see.

The input and output will be
`std::uint8_t, std::optional<std::vector<uint8_t>>`.

This represents `subcommand` and any input data.

Changes to note,
- all subcommand in the request/response struct are removed. It will be
managed by the wrapper directly.
- Unit tests checking for input with only the subcommand are
removed.
- Move all reply struct to header files to be accessible in unit test.

Tested:
All IPMI OEM command still works the same as before this change.

Add sys command for powercycle on host shutdown.

The new command will trigger a power cycle the next time the host shuts
down. This can exist in parallel with the existing mechanism to trigger
a power cycle after a specified time interval.

The implementation of host state detection and power cycling is platfrom
specific; the new command will just add a temporary file that marks the
system ready to powercycle on the next shutdown. Usually, a systemd unit
would be enabled by the presence of this file to handle the power
cycling process.
