gdbarch: use predefault for more value components within gdbarch
For some reason the following value components of gdbarch:
bfloat16_format
half_format
float_format
double_format
long_double_format
so_ops
All use a postdefault but no predefault to set the default value for
the component.
As the postdefault values for these components are all constant
pointers that don't depend on other fields within the gdbarch, then I
don't see any reason why we couldn't use a predefault instead.
So lets do that.
