boards/stm32f3: nucleo-f302r8:ihm07m1_b16: enable LTO to fit flash
The ihm07m1_b16 (FOC motor control) configuration overflows the
STM32F302R8 64 KiB flash region by ~470 bytes, so it no longer links.
Enable GNU Full LTO (CONFIG_LTO_FULL=y); cross-module dead-code
elimination brings the image back under the limit (flash drops from
~66.0 KiB to ~57.7 KiB, 88%).
