fix(cmake/bazel/clang): remove finite-math-only opt from Ofast,

for keep same build between gcc and clang

more detail:
```
 printf("%d\n", std::isnan(std::numeric_limits<float>::quiet_NaN()));
 printf("%d\n", std::isnan(std::nan("1")));
```

linux-clang and android-NDK clang have diff build logic with gcc and
macos/windows clang/clangcl
* clang++-12 -Ofast 1.cc
output is:
0
0

* clang++-12 -Ofast 1.cc -fno-finite-math-only
output is:
1
1

* g++ -Ofast 1.cc
output is:
1
1
