filetype: add STM32 image type
Both STM32MP BootROM and TF-A first stage expect subsequent bootloader
stages to feature a specific 256-byte long STM32 file header.
Add detection of the header to file_detect_type().
While there's only one version of the header so far, identify the new
header as v1 anyway, so new versions can be unambiguously added.
