Commit message:

Reduce excessive warning verbosity in MSVC builds

This change eliminates _some_ kinds of spammy MSVC compiler warnings originating from third-party libraries, such as:

```
external/grpc+/src/core/lib/channel/channel_stack_builder.cc(52): note: see reference to function template instantiation 'std::_Optional_destruct_base<_Ty,true>::_Optional_destruct_base<__int64>(std::in_place_t,__int64 &&) noexcept' being compiled
        with
        [
            _Ty=int
        ]
```

There are still several other classes of spammy warnings that should be silenced or fixed, such as:

```
(22:34:11) INFO: From Compiling c/blake3_avx512_x86-64_windows_msvc.asm:
MASM : warning A4018:invalid command-line option : /bigobj
```

```
(22:34:14) INFO: From Compiling absl/time/internal/cctz/src/time_zone_fixed.cc [for tool]:
cl : Command line warning D9025 : overriding '/W3' with '/w'
```
Note that Bazel-intrinsic code (i.e. things that are not third-party included libraries) will still throw these warnings.
