Base-Toolchain: update project_config

In GCC 11 the column numbers default to being column numbers, respecting
multi-column characters. The old behavior can be restored using a new
option -fdiagnostics-column-unit=byte. There is also a new option
-fdiagnostics-column-origin=, allowing the pre-existing default of the
left-hand column being column 1 to be overridden if desired (e.g. for
        0-based columns). The output of -fdiagnostics-format=json has
been extended to supply both byte counts and column numbers for all
source locations.
