Component: flash parameter storage on stm32h7. Fixes PX4#15331.

As per the discussion in PX4#15331, fixed issue where stm32h7 chips use hardware ECC bits in program memory that disallow overwriting 32-byte flash line that has already been written. As such, this change allows for a variant implementation of the flashfs system that uses more space in the flash entry header in order to allow an entire line to be reserved for erasing an entry.
