Clang-format with GNU style splits up three-way comparison operator

[Halalaluyafail3]

Clang-format with GNU style doesn't recognize three-way comparison operators and will split them up. For example:

1<=>2;

Clang-format with GNU style will format this to:

1 <= > 2;

This is ill-formed and shouldn't be generated.

Same root cause as #58435

The GNU option sets the C++ standard when parsing to C++03, where three-way comparison operators didn't exist; therefore the clang parser doesn't see them as such.

This is fixed by adding Standard: Latest in your config

Ok that does solve the problem, is there any reason to not make this the default behavior (or at least, not splitting up <=>)?
