b258535161 Treat libunwind sandbox as a ~regular sandboxee
This removes dependency on unwind from forkserver,
which should reduce binary size for all the custom forkservers (also the SAPI generated ones).

c501379056 Clang tool: Prevent extra nesting of namespaces
When specifying the `namespace` argument in Bazel (`NAMESPACE` in CMake), the
Clang tool used to put _all_ dependent types in that namespace.

For a declaration of `namespace a::b { struct S {...};` and a `namespace`
argument of `a::b`, this means that the header output was similar to
```
namespace a::b {
namespace a::b {
struct S { ...
```

This was never intended and also does not match the Python based header
generator. The Clang tool now "merges" those same namespaces. This is
correct, as it processes `namespace`d spellings with their full namespace
path.

ae3d334cc2 generator2: Skip anonymous structs/unions
The Python code has been relying on `spelling` to return `None` for skipping
anonymous structs/unions.

libclang has been returning a "spelling" for those for a while now (LLVM 16
introduced this in its branch in 2022), though, so this check no longer works.
Use the correct method `clang.CIndex.is_anonymous()` instead.
