efi_loader: optional data in load options are binary
The field boot OptionalData in structure _EFI_LOAD_OPTIONS is for binary
data.
When we use `efidebug boot add` we should convert the 5th argument from
UTF-8 to UTF-16 before putting it into the BootXXXX variable.
When printing boot variables with `efidebug boot dump` we should support
the OptionalData being arbitrary binary data. So let's dump the data as
hexadecimal values.
Here is an example session protocol:
=> efidebug boot add 00a1 label1 scsi 0:1 doit1 'my option'
=> efidebug boot add 00a2 label2 scsi 0:1 doit2
=> efidebug boot dump
Boot00A0:
attributes: A-- (0x00000001)
label: label1
