Pivok d0b39c7f2b libzigc: hypot (#31104) 
First time contribution.

Implements hypot for libzigc #30978.

Commands i run:
```
$ stage3/bin/zig build -p stage4 -Denable-llvm -Dno-lib

$ stage4/bin/zig build test-libc -Dlibc-test-path=../../libc-test -Dtest-filter=hypot --summary line -fqemu -fwasmtime
Build Summary: 725/737 steps succeeded (12 skipped)
```

I also changed std.math.hypot becuase some libc-tests raised fp exceptions. Example:
```
../../libc-test/src/math/special/hypot.h:8: bad fp exception: RN hypot(0x1p-1074,0x0p+0)=0x1p-1074, want 0 got INEXACT|UNDERFLOW
../../libc-test/src/math/special/hypot.h:9: bad fp exception: RN hypot(0x1p-1074,-0x0p+0)=0x1p-1074, want 0 got INEXACT|UNDERFLOW
```

I also run this command as a quick sanity check:
```
$ stage4/bin/zig build test-std -Dtest-filter=hypot -Dtest-target-filter=x86_64-linux-musl --summary line
Build Summary: 5/5 steps succeeded; 136/136 tests passed
```
