target: Move task tag into struct se_cmd + support 64-bit tags
Simplify target core and target drivers by storing the task tag
a.k.a. command identifier inside struct se_cmd.
For several transports (e.g. SRP) tags are 64 bits wide.
Hence add support for 64-bit tags.
(Fix core_tmr_abort_task conversion spec warnings - nab)
(Fix up usb-gadget to use 16-bit tags - HCH + bart)
