Adds conditional exports - __fixkfti - __fixunskfti - __floattikf - __negkf2 - __mulkc3 - __divkc3 - __powikf2 and adjusts tools/gen_stubs.zig. From https://gcc.gnu.org/onlinedocs/gcc/Floating-Types.html: "When long double transitions to __float128 on PowerPC in the future, __ibm128 will remain for use in conversions between the two types." Hence `__extendkftf2` and `__trunctfkf2` for conversion are superfluous and only using f128 for `kf` routines is justified. Closes #16057.
