Add automatic TID derivation in test_common.sh based on the script
filename. The TID is extracted by stripping the "test_" prefix and
".sh" suffix from the script name (e.g., test_loop_01.sh -> loop_01).
This removes the need for each test script to manually define TID,
reducing boilerplate and preventing potential mismatches between
the script name and TID. Scripts can still override TID after
sourcing test_common.sh if needed.

Add ublk stripe target which can take 1~4 underlying backing files
or block device, with stripe size 4k ~ 512K.
Add two basic tests(write verify & mkfs/mount/umount) over ublk/stripe.
This target is helpful to cover multiple IOs aiming at same
fixed/registered IO kernel buffer.
It is also capable of verifying vectored registered (kernel)buffers
in future for zero copy, so far it isn't supported yet.
Todo: support vectored registered kernel buffer for ublk/zc.
