Fix FW_COMMIT_HASH compiler warning 

On my end, the default length for the abbreviated commit hash is 9 characters.
This won't fit into uint32_t (4 bytes).

Instead change FW_COMMIT_HASH into a string
and create preprocessor symbol for the string length
such that it's known at compile time.

If the string should be longer or shorter
then only FW_COMMIT_HASH_LENGTH needs to be configured on the CMake side
