This change merges the internal version of `sapi.bzl` with the external version again:
- Add more docstrings to the various macros
- Skip creation of `.isystem` file, get info from toolchain instead

This fixes the main issue (#118) with stack traces on Fedora, which uses a
`/lib64` and `/usr/lib64`.

This uses the Google formatting style to format the prototype comments, with an
internal line length of 75, which accomodates the indentation in the generated
API class.

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.

The enclosing type is enough to reconstruct the AST when writing the header and this
change avoids emitting the same struct twice.

This is a follow up to fa9e6e8a5c.
Drive-by:
- Replace deprecated calls to `getNameAsString()`

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.
The feature is pure optimization, but it requires
additional syscalls.

There are a lot of internal users depending on the old behavior of the
libclang-based generator.

The constexpr functions can be used to ensure that all branches actually compile
(unlike plain preprocessor `#ifdef`s).

munmap is widely used by sanitizer, but it
probably works for Asan/Msan because it's enabled
by unrelated Allow* call.
Move mprotect to shared part as well. It will be
needed for compress_stack_depot.

Use [`direct_headers`](https://bazel.build/rules/lib/CompilationContext#direct_headers)
from the Bazel/Blaze compilation context instead of _all_ transitive headers.
For the clang based generator, this means we don't try to parse
`textual_headers`, which will fail (they are by definition not
stand-alone, after all).
