Add D-Bus Raw PECI Daemon This adds a new D-Bus daemon to handle raw PECI requests over D-Bus. The D-Bus interface provides a Send method that takes a vector of byte vectors where each byte vector contains the raw data for a single PECI command. This allows sending an array of raw PECI commands to execute in bulk to avoid issues with network latency when sending multiple commands. The method returns a vector of raw PECI responses corresponding to the vector of raw commands. Tested: Confirmed that a single and multiple PECI commands correctly execute and return when SendRawPeci is called. Change-Id: I6b2d0f81366ea77057e70d69c72be90ba4c4aeb9 Signed-off-by: Jason M.

libpeci is a library that provides various APIs to interface with the IOCTLs provided by the PECI driver in the OpenBMC kernel. Currently available here:
https://github.com/openbmc/linux/blob/dev-5.4/include/uapi/linux/peci-ioctl.h
This repo also includes a peci_cmds command-line utility with functions that map to the libpeci APIs. It can be used to test PECI functionality across the library, driver, and hardware.
This repo also includes dbus_raw_peci which provides a raw-peci daemon that exposes a raw PECI interface that is accessible over D-Bus. It can be used when an application needs to send a raw PECI command without loading the full PECI library.
