c: Don't pedwarn on _FloatN{,x} or {f,F}N{,x} suffixes for C2X
Now that _Float{16,32,64,128,32x,64x,128x} and
{f,F}{16,32,64,128,32x,64x,128x} literal suffixes are in C23 standard,
I think it is undesirable to pedwarn about these for -std=c2x, so this
patch uses pedwarn_c11 instead. In c-family/, we don't have that function
and am not sure it would be very clean to define dummy pedwarn_c11 in the
C++ FE, so the patch just does what pedwarn_c11 does using pedwarn/warning.

gcc/c-family/
* c-lex.cc (interpret_float): For C diagnostics on FN and FNx suffixes
append " before C2X" to diagnostics text and follow behavior of
pedwarn_c11.
gcc/c/
* c-decl.cc (declspecs_add_type): Use pedwarn_c11 rather than pedwarn
for _FloatN{,x} diagnostics and append " before C2X" to the diagnostic
text.
