We need to pass a non-empty buffer into the read routine because
the return code EFI_BUFFER_TOO_SMALL is expected only for directories.
Properly, the right way is to retrieve file size using FatGetInfo or 
FileGetInfo,  but this will significantly slow down the fuzzing process,
that's why we use  100-byte temporary buffer

Optionally allow .contentVisibility in same boot fs root locations
as searched for .VolumeIcon.icns, since file next to boot.efi is
deleted on macOS update.

OcBootManagementLib: Add InstanceIdentifier, and ability to target .contentVisibility to specific instances
