user_layer: Add get/set user payload access.

IPMI Spec reference: Section 24.6, 24.7.
Support is added to get/set user access details for the
unreserved, supported payload types defined by Spec.
SOL is the only unreserved, supported payload currently.
If support is needed for unreserved std/oem payload
types in future, they can be enabled with minor source code
changes to this implementation.

All payload types are packed in a JSON object
"payload_enabled" in ipmi_user.json file.

Tested-by:
1. For user 8 in channel 3, Enable SOL payload.

   // Command - (channel 3 is of LAN channel type)
   ipmitool  -I lanplus...raw 0x06 0x4C 3 0x8 0x02 0 0 0
   // Verify it with Get User Payload Access Command
   ipmitool  -I lanplus...raw 0x06 0x4D 3 8
   02 00 00 00 // Response

2. Disable SOL payload.

   // Command
   ipmitool  -I lanplus...raw 0x06 0x4C 3 0x48 0x02 0 0x00 0
   // Verify it with Get User Payload Access Command
   ipmitool  -I lanplus...raw 0x06 0x4D 3 8
   00 00 00 00 // Response

3. Enable unsupported payload stdPayload7.

   // Command
   ipmitool  -I lanplus...raw 0x06 0x4C 3 0x8 0x80 0 0 0
   Error: Invalid data field in request // Response
