Lu Ken 4c76565b6c efi/tpm: Add EFI_CC_MEASUREMENT_PROTOCOL support 
The EFI_CC_MEASUREMENT_PROTOCOL abstracts the measurement for virtual firmware
in confidential computing environment. It is similar to the EFI_TCG2_PROTOCOL.
It was proposed by Intel and ARM and approved by UEFI organization.

It is defined in Intel GHCI specification: https://cdrdv2.intel.com/v1/dl/getContent/726790 .
The EDKII header file is available at https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Protocol/CcMeasurement.h .

Lu Ken ef8679b645 commands/efi/tpm: Use grub_strcpy() instead of grub_memcpy() 
The event description is a string, so using grub_strcpy() is cleaner than
using grub_memcpy().

1. Use macro GRUB_ERR_NONE instead of hard code 0.
2. Keep lowercase of the first char for the status string of log event.
