XL: Add comment clarifying why we pretend it has full C++11/14 support
Since commit b0f46c48f6 (CompileFeatures: Now able to presume full
language level support, 2019-03-06, v3.15.0-rc1~265^2~1) we pretend that
the XL compiler has full C++11 and C++14 support so that projects
specifying granular features will at least get the corresponding
compiler mode. This is a work around for our lack of a full feature
check table for this compiler that works in common cases. Add a comment
explaining this.
Issue: #20521
