Add MTM BMC Feature Control IPMI command

Certain features having security concerns needs to be enabled/disabled
only in manufacturing mode. Add a command to support the same for MCTP
feature.

In addition to starting or stopping a service, add an option to enable
or disable a service which will persist across AC cycles.

Request bytes:
Byte 1 – Supported features
     00h - MCTP
     01h to FFh - reserved (will be adding support for more features
as needed)
Byte 2 – Enable/Disable feature
    00h – Stops the given feature
    01h – Starts the given feature
    02h - Disables the given feature
    03h - Enables the given feature
    04h to FFh – reserved
Byte 3 - Custom feature arguments
  When byte 2 value is 00h:
    00h - MCTP over PCIe
    01h - MCTP over SMBus HSBP
    02h - MCTP over SMBus PCIe slot
    03h to FFh - reserved
Byte 4:5 – reserved

Tested:
Verified MCTP feature can be enabled/disabled as expected in MTM mode
the change will persist across AC cycles.
