pdr: Implement terminus locator PDR for BMC

This commit creates the TL PDR for the BMC. The TID and MCTP EID for
BMC is static, 1 and 8 respectively. BMC PDRs are assigned the value
of 1 for PLDMTerminusHandle. Added the parser for terminus locator
PDR in pldmtool.

Tested:

/tmp/pldmtool platform GetPdr -d 0

nextRecordHandle: 2
responseCount: 19
recordHandle: 1
PDRHeaderVersion: 1
PDRType: 1
recordChangeNumber: 0
dataLength: 9

PLDMTerminusHandle: 1
validity: valid
TID: 1
containerID: 0
terminusLocatorType: MCTP_EID
terminusLocatorValueSize: 1
EID: 8
