Merge #19617: doc: Clang 8 or later is required with FORCE_USE_SYSTEM_CLANG
e60ef21b8a0f62ebc2e0bdbb5943fa80cc4d98b2 doc: Clang 8 or later is required with FORCE_USE_SYSTEM_CLANG (fanquake)
Pull request description:
The usage of pragmas within the macOS SDK requires LLVM Clang 8. This is
the same version as our prebuilt Clang, however the minimum is worth noting
here as they may diverge and/or expert users might expect they could use an
earlier version.
If you compile depends using `FORCE_USE_SYSTEM_CLANG=1` and Clang 7 you'll see output like:
```bash

I've got a [godbolt here](https://godbolt.org/z/j6r987) that contains a demo of the issue (based off the macOS SDK). It will compile with Clang 8 but not with Clang 7.
