soc: st: stm32n6: invoke signing tool in silent mode

Browse source 
The STM32 signing tool (STM32_SigningTool_CLI) is invoked as a post-build
command to generate a signed Zephyr binary, which is required to run from
flash on N6 series. If the file specified as output already exists, the
tool will by default prompt to confirm it should be overwritten. However,
when invoked from the build system rather than a terminal, this prompt
will break the build (freeze during the "Linking zephyr.elf" step). This
can be seen by building the same application twice in a row, as the second
build will not be different enough to make the build artifacts be deleted
and thus the (old) signed image will be seen by the tool.

Invoke the tool in silent mode such that user is never prompted. This fixes
build failures while still working as intended (if present, the existing
signed image will get overwritten properly).
