Set `SAPI_CLANG_TOOL_EXECUTABLE` to specify the location of a pre-built Clang
tool based header generator.

CMake already provides `CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES`, so there's
no need to invoke the compiler to determine system include directories.
For the Clang tool based header generator, adding the includes from the
current toolchain is strictly more correct than having it try and figure them
out itself (which will favor files from any installed libc++ and/or Clang).

`SAPI_ENABLE_GENERATOR` => `SAPI_ENABLE_CLANG_TOOL`
This prepares further changes in this area.

This finally prevents Ninja from rebuilding everything needlessly each time a
CMake reconfiguration was triggered. The root cause is that we used
`file(WRITE ...)`, which always unconditionally overwrites, so Ninja sees
those files as "dirty".

The generated `compile_commands.json` contains everything that the interface
generator needs.

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.

Newer versions of the GNU gold linkers sometimes omit the symbols for
sandboxed functions, leading to errors like `function not found` when
Sandboxed API tries to call them at runtime.
The fix is simple: Do what Bazel does and wrap the static library in
a `-Wl,--whole-archive`/`-Wl,--no-whole-archive` pair.

Addresses #104 and also fixes a TODO to use `target_link_options()`
and the `LINKER:` prefix in the SAPI build defs.

This allows resource-constrained environments to benefit from the
space savings of dynamic linking. This is not meant to be used in
the general case.

- Better testability
- Support for the `--sapi_isystem` argument, same as the Python generator

The Bazel build already queries the current toolchain for its system include
directories. This change brings feature parity and is necessary for systems
with unusual include locations.

Add the location of the Python 3 interpreter to the CMake cache so
that its available in the `add_sapi_library()` macro in downstream
embedding projects.

This fixes some CMake-3.12+-isms, like `list(JOIN ...)` and setting link
properties on OBJECT libraries.

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.
