libzigc: implement modff
...
`modf` function was generalized and renamed to `modfGeneric`, `modf` and
`modff` provide the appropriate type while calling that function. The
unit tests were also generalized so they can be reused for different
float types.
Both `modf` and `modff` were tested after making these changes:
```
$ stage4/bin/zig build test-libc -Dlibc-test-path=<LIBC-TEST-PATH> -Dtest-filter=modf -fqemu -fwasmtime --summary line

libzigc: Implement modf
...
The behaviour regarding special cases differs between `libc` and Zig's
`stdlib` for `modf`, so the implementation couldn't be a straightforward
calling of `stdlib` function.
Other than the obvious documented differences, I also had problems with
the `INVALID` flag being raised while running `libc-test` suite on riscv
arch through qemu. The solution was to test if the argument is `NaN`,
and then return a quiet `NaN` if so.
Passing tests, that should include all the special cases to be wary of,
were also added.
Test results:
```
$ stage4/bin/zig build test-libc -Dlibc-test-path=<LIBC-TEST-PATH> -Dtest-filter=modf -fqemu -fwasmtime --summary line
Build Summary: 921/921 steps succeeded

libzigc: posix_{fadvise, fallocate}, fallocate
...
This commit removes `posix_fadvise`, `posix_fallocate`, and `fallocate`
from the bundled musl by forwarding to Zig's wrappers. `musl`'s
implemenation does not use `__syscall_cp`, so I assume trivially
replacing these functions is okay.
For `posix_fadvise`, `musl` notes that the arguments are reordered
for ARM and other architectures. Zig's wrapper already handles this
case.

libzigc: hypot ( #31104 )

First time contribution.
Implements hypot for libzigc #30978 .

```

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

stage4/bin/zig build test-libc -Dlibc-test-path=../libc-test -Dtest-target-filter=x86_64-linux-musl
```
and the tests passed.
I'm planning on doing more once I get the hang of it.
