tcl/stm32l5x|u5x: support HLA adapters in non-secure mode only 

instrument "target/stm32x5x_common.cfg" used by both STM32L5x/U5x
to support HLA adapters like "interface/stlink.cfg" in non-secure mode

if the device switches to secure mode, the debug session will be
stopped immediately (with an explanatory message).
