Add testboard openocd config
What changed, and why it matters
This commit adds a configuration file for OpenOCD, a debugging tool used during hardware development and testing. It tells the debugger how to connect to an STM32U5 test board using a J-Link adapter. There is no change to firmware code, no user-facing feature, and no security-relevant behavior.
No security action needed. Treat as normal development tooling change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The new file scripts/stm32u5g9z-testboard.cfg is an OpenOCD board/target script. It sources the J-Link interface config, selects SWD transport, configures reset behavior, sources the STM32U5 target config, sets a physical work-area address beyond RTT buffers, and sets the adapter speed. It is purely a development/debugging aid and does not alter runtime firmware logic, cryptography, or device behavior.
