- Move CMake superbuild files
- Drop use of `CMakeLists.txt.in` configure files
- Allow overriding dependency directories. For now, this should only be
used by GitHub workflows. Will be expanded on later, possibly renaming
the variables.
This change is one in a series to make it easier to consume/customize
Sandboxed API in downstream projects.

- Update `.gitignore` to ignore clangd's `.cache` directory

This removes our own fork of `absl::StatusOr<>`. Sandboxed API still includes
a custom matcher for Googletest, as that is not open source yet. For
compatibility, the `statusor.h` header is still retained and now aliases
`sapi::StatusOr<>` to `absl::StatusOr<>`.

This is done by simply building libffi in-tree. Normally, this is not
desirable, but in our case is actually ok, as this is an external
dependency to be pulled in and cleaning the source tree is easy in this
case.

When using SAPI from an external project via CMake, the small zlib patch
cannot be found during the config phase.
This change also fixes an oversight in that the tests depend on some of
the example code.
Regardless embedding code should set `SAPI_ENABLE_EXAMPLES` to `OFF`.
Disabling tests by setting `SAPI_ENABLE_TESTS` to `OFF` stays optional.

Similar to what the Bazel build does, this change adds zlib as an additional

Abseil insists on having a Google Test directory, even if we're not going to
run (or even build) the tests.
This changes forces all test settings to `OFF` just for Abseil, allowing
SAPI builds to complete normally. Embedding projects should not be affected,
if they already included Abseil.

When embedding SAPI in an external CMake project, the version of
`protobuf_generate_cpp` that we lifted from upstream protobuf produces
the wrong generated file paths.
For example, given this project structure:
```
/parent/
+-- myproject/
+-- myproject_build/ <- CMake build directory
+-- sandboxed-api/ <- Checkout from GitHub
```
And a CMake file in `myproject/CMakeLists.txt` that embeds SAPI like
this:
```
cmake_minimum_required(VERSION 3.12)
project(SandboxedTest LANGUAGES CXX)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
add_subdirectory(
${PROJECT_SOURCE_DIR}/../sandboxed-api
${PROJECT_BINARY_DIR}/sandboxed-api
)
```
Then `protobuf_generate_cpp` correctly invokes the protoc compiler to
generate
`/parent/myproject_build/sandboxed-api/sandboxed_api/proto_arg.proto.pb.cc'.
However, the path of the generated source file that is passed to the C++
compiler will be
`/parent/myproject_build/sandboxed-api/sandboxed_api/../../myproject_build/sandboxed-api/sandboxed_api/proto_arg.pb.cc`.
Note the duplicated project build directory component in the
canonicalized version:
`/parent/myproject_build/myproject_build/sandboxed-api/sandboxed_api/proto_arg.pb.cc`.
This change simple omits the computation of any relative file paths and
simply uses `_pb_PROTOC_OUT_DIR` which defauls to
`CMAKE_CURRENT_BINARY_DIR`, which should always contain the correct
path.

This change moves away from a classical superbuild which downloads and builds
at build time. Instead, we now follow a "Fetch Content" workflow (available as
FetchContent in CMake 3.11+) and download dependencies at config time.
Rationale: Superbuild projects have the disadvantage that projects cannot
directly access their individual declared targets. This is not a problem with
regular libraries, as those are usually/supposed to be installed. With
Sandboxed API, this is not desirable, as it has dependencies like Abseil and
glog, which are almost always consumed by including their source tree using
add_subdirectory().
Fixes#10 and makes external embedding easier.
