jtag/drivers/cmsis_dap: speed up long transfers using DAP_TransferBlock
DAP_TransferBlock command saves n - 3 bytes in comparison to DAP_Transfer,
where n is number of transfers.
Use DAP_TransferBlock optionaly to save some USB bandwidth.
The change increases the speed of the write transfer
from 40 KiB/s to 42 KiB/s @ USB FS, adapter speed 1000.
