4b2c730c5e Bazel: Make generator configurable
This change introduces an experimental `generator_version` attribute to the
`sapi_library()` rule. Version `1` will select the current interface
generator, which is based on libclang and Python. Setting the attribute to
version `2`, will select the newer interface generator written in C++ that
uses a full clang compiler frontend for parsing. Both emit equivalent header
output, differences in parsing and/or edge cases notwithstanding.

The default, as of now, is still the old version `1` generator.

Note: CMake allows to select the new interface generator globally by setting
`SAPI_ENABLE_GENERATOR`.

74bb2c35ca bazel: Add build rules for the new interface generator
This adds a workspace rule that inspects the current system first and
downloads a suitable version of LLVM/Clang from GitHub if it can't
find one. In the latter case, the necessary parts are build from source,
which can take a while (~10-15m, depending on the build machine).

In order to be found, LLVM/Clang system libraries must be version 11
or higher. On Debian/Ubuntu, install `llvm-13-dev` and `libclang-13-dev`.

The new `llvm_config.bzl` implements this logic. It is loosely based on
upstream's https://github.com/llvm/llvm-project/blob/main/utils/bazel/configure.bzl.
Note that due to the way Bazel separates local repositories, we have to
duplictate some of this code.

dc895f6dc8 Introduce an API version to the build rules
This will allow us to experiment with (and subsequently migrate to)
changes to the generated API, possibly incompatible ones.

This change should be a no-op for current builds, as there is only
a single version of Sandboxed API.

e8fe398340 clang_generator: Enable mixed header processing
This implements a custom compilation database to conditionally add the correct
language flags to the compiler frontend. Otherwise, a C header might receive
`--std=c++17` and fail.

Note: All headers are always processed in C++ mode. We expect that headers of
well-behaved C libraries contain `#ifdef __cplusplus`/`extern "C" {}` guards.

5416cbb141 Introduce SAPI_ASSERT_OK
We have a SAPI_ASSERT_OK_AND_ASSIGN which corespondents to
SAPI_ASSIGN_OR_RETURN.

We also have SAPI_RETURN_IF_ERROR but we don't have a coresponding
macro for ASSERT.

I think that this completes the API and makes writting tests a little
bit simpler.
