Process a firmware volume and create a volume handle.
Create a volume handle from the information in the buffer. For
memory-mapped firmware volumes, Buffer and BufferSize refer to
the start of the firmware volume and the firmware volume size.
For non memory-mapped firmware volumes, this points to a
buffer which contains the necessary information for creating
the firmware volume handle. Normally, these values are derived
from the EFI_FIRMWARE_VOLUME_INFO_PPI.
@param This Points to this instance of the
EFI_PEI_FIRMWARE_VOLUME_PPI.
@param Buffer Points to the start of the buffer.

handle. The firmware volume handle must
