f2048d028f Clang tool: Force-undefine feature preprocessor defines
To avoid code that is being parsed to include the intrinsics headers, undefine
a few key preprocessor defines.

67bc67bbef clang_generator: Handle inter-type dependencies better
This change changes the emitter to work on `clang::TypeDecl`s instead of
`clang::QualType`s, as the latter only describe complete definitions. This
allows us to better deal with situations where we would otherwise have a kind
of circular type dependencies: For example, a `typedef` that depends on a
`struct` which in turn has a member that references the typedef.
For this to work, we now also record the actual source order of declarations,
similar to what the libclang based header generator does.

Also add some more tests for the newly covered cases.

4b56d5606d clang_generator: Fail header generation with struct-by-value
The libclang based header generator disallows functions that pass structs (or
more generally "record types") by value. While this can be implemented, the
such functions as emitted by the clang_generator never worked.

We should revisit this when we implement support for passing 128-bit integer
types directly, as those will work the same as small structs.

39a1bc9d7a Skip system headers in Clang generator
When not requesting any particular function, `sapi_library()` will try and
make available _all_ functions it finds. In this case, system headers should
be skipped to avoid inflating the API surface. Standard library functions
can still be manually requested by adding them to the `functions` (Bazel)/
`FUNCTIONS` (CMake) argument.

dbaf95c724 Move utility code into sandboxed_api/util
This change should make it less confusing where utility code comes from.
Having it in two places made sense when we were debating whether to publish
Sandbox2 separately, but not any longer.

Follow-up changes will move `sandbox2/util.h` and rename the remaining
`sandbox2/util` folder.

afa232cc17 Clang generator: Remember "seen" types when collecting related types
This change includes a small refactoring to remember which types the generator
has already seen during header generations. Otherwise we may loop indefinitely
on certain complex types. One such type is `std::FILE` in Clang's libc++.
