ARM:Add Jtag to Dormant sequence in case the target has both jtag and swd

[mean00]

Detailed description

• The current Dormant to SWD code manages correctly the case where SWD is default/the only interface
• If the chip has both SWD & Jtag and default is Jtag, it lacks the Jtag->dormant sequence and does not work
• The proposed patch adds that sequence

For what i could see, it still works with RP2040 and older Arm chips i have (STM32F1/GD32F3) Tested on a chip with both Jtag & SWD/Default jtag + Debug Protocol v3, it works with the change, doesnt without

NB: Not completely sure the 8 trailer '1' bits are really needed, it works fine with, was there in the demo code
