Pull request overview

Updates the benchmarking and emulation tooling to support running boot-time benchmarks from a Raspberry Pi against an STM32H5/H563 target, plus associated build/config tweaks to enable consistent timing and sizing measurements.

Changes:

• Add a new libgpiod-based boot-time measurement script and switch the benchmark runner to OpenOCD + GPIO edge timing.
• Introduce build flags (WOLFBOOT_TEST_FILLER, WOLFBOOT_TIME_TEST) and early-boot GPIO toggling to support boot-time measurements.
• Adjust emulation linker templates and config-generation flow for multiple targets (STM32*, nRF, MCX).
