f44cca6c98 Fix path to generated proto sources when embedding
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.

edd6b437ae Filter functions based on files we scan.
Currently we extract all functions from the compilation unit - it doesn't really make sense as it will try to process functions in included files too.
As we require sapi_in flag, we have information which files are of interest.

This change stores the top path in _TranslationUnit and uses it when looking for function definitions to filter only functions from the path we provided.

6332df5ef6 Fix or ignore type errors generated by the next release of pytype.
The next release contains one major change: for function parameter annotations,
pytype will no longer treat (x: X = None) as equivalent to
(x: Optional[X] = None). This pytype behavior was based on an outdated version
of the type-checking spec. Annotations that were relying on the behavior now
need to explicitly declare themselves as Optional.
