LIO is going to want to do the same block to/from SCSI pr types as sd.c
so this moves the sd_pr_type helper to a new file and adds a helper to
go from the SCSI value to the block one.

The next patches allow us to call the block layer's pr_ops from the
backends. This will require allowing the backends to hook into the cmd
processing for SPC commands, so this renames sbc_ops to a more generic
exec_cmd_ops.

This adds support in dm for the block PR read keys and read reservation

This adds support for the block PR callouts to target_core_iblock. This
patch doesn't attempt to implement the entire spec because there's no way
to test it all. It only supports what's required for windows clustering
right now.

Rename sd_pr_command to sd_pr_out_command to match a
sd_pr_in_command helper added in the next patches.

Add callouts for reading keys and reservations.
Note: This only initially adds the struct definitions in the kernel as I'm
not sure if we wanted to export the interface to userspace yet. We may
want to refine internally for LIO and when we can enable it for NVMe then
add the finished interface to
