libcamera: log: Use compiler builtins to retrieve file and line number

Replace the __FILE__ and __LINE__ values passed to the _log() function
with default parameters, taking their values from the __builtin_FILE()
and __builtin_LINE() functions. This moves handling of the file and line
from the preprocessor to the compiler, which is generally preferred as
it increases type safety.
