Add support for TP 4065 ("Simple Copy Command").
Changes for v4
* merge for-loops (Keith)
Changes for v3
* rebased on nvme-next
* changed the default msrc value to a more reasonable 127 from 255 to
better align with the default mcl value of 128.
Changes for v2
* prefer style that aligns with existing NvmeIdCtrl field enums
(Minwoo)
* swapped elbat/elbatm fields in copy source range. I've kept the R-b
and A-b from Minwoo and Stefan since this is a non-functional change
(the device does not use these fields at all).

Add support for TP 4065a ("Simple Copy Command"), v2020.05.04
("Ratified").
The implementation uses a bounce buffer to first read in the source
logical blocks, then issue a write of that bounce buffer. The default
maximum number of source logical blocks is 128, translating to 512 KiB
for 4k logical blocks which aligns with the default value of MDTS.
