Eugene Siegel a0992a842e log: use std::source_location in place of __func__, __FILE__, __LINE__ ...

The std::source_location conveniently stores the file name, line number,
and function name of a source code location. We switch to using it instead
of the __func__ identifier and the __FILE__ and __LINE__ macros.

BufferedLog is changed to have a std::source_location member, replacing the
source_file, source_line, and logging_function members. As a result,
MemUsage no longer explicitly counts source_file or logging_function as the
std::source_location memory usage is included in the MallocUsage call.

This also changes the behavior of -logsourcelocations as std::source_location
includes the entire function signature. Because of this, the functional test
feature_config_args.py must be changed to no longer include the function
signature as the function signature can differ across platforms.
