Originally CameraHalManager is created in the libcamera start up
and destroyed in the libcamera termination. However,
CameraHalManager destructor can access other static objects that
has been destroyed.
Avoid this issue by destroying CameraHalManager when tear_down() is
called in ChromeOS or leaking it in other platforms.

On gcc versions older than 9, the file system library, used by the
Android camera HAL configuration file parser, is implemented in a
separate static library. Furthermore, on gcc 7, it's provided in the
std::experimental namespace. This breaks compilation of the HAL on gcc
7, and linking on gcc 8.
Fix the compilation issue by conditionally including
<experimental/filesystem> and creating a namespace alias in std, and the
link issue by linking to libstdc++fs on gcc versions older than 9.
The inclusion of <experimental/filesystem> is a bit of a hack, and when
we'll start using the file system library in another compilation unit,
we should then move all this to an internal helper to abstract the
compiler version.

The HAL layer was getting the min and max frame durations from the
camera, then rounding it to fps to report as available fps ranges. The
same min and max frame durations were then being reported as min and max
frame durations. Since the fps are integer values while the frame
durations are in ns, this caused a rounding error making it seem like we
were reporting an available max fps that was higher than what was
allowed by the minimum frame duration.
An example is if the minimum frame duration is reported as 33366700ns.
The HAL layer would then convert it to fps, which is 29.97, but it would
be rounded and reported as 30 fps. When 30 fps is converted to a frame
duration it is 33333333ns, which is less than the minimum frame duration
that we report. Thus the minimum frame duration that we report
contradicts the fps range that we report.
Fix this by recalculating the frame durations based on the rounded fps
values.
This allows the following CTS test to pass:

When stopping the camera worker, queuedRequest() calls may have queued
asynchronous function invocation messages to the worker thread, and some
of those messages may not have been processed yet. The messages will
stay in the thread's queue until the camera worker is restarted (when
the camera service will start a new capture session). At that point,
they will be dispatched, which will cause a crash due to the
CaptureRequest passed to processRequest() having been deleted by
CameraDevice::stop() calling descriptors_.clear().
Fix this by forcing dispatching of all function invocation messages when
stopping the camera worker thread. Note that this is inherently racy, as
more queueRequest() calls may arrive from the camera service while we're
stopping. This race condition will be addressed by a subsequent patch
series.

The CameraMetadata::updateEntry() functions cast the data pointer to a
void pointer, which is then used internally to call
update_camera_metadata_entry(). If the caller passes a pointer to an
incorrect data type, the behaviour is undefined, with possible crashes
if the incorrect data type is smaller than expected by the Android
metadata library.
To avoid crashes, make all public updateEntry() functions take typed
pointers, and pass the element size to the internal function. The
element size is then checked against the expected size, and an error
message logged if they don't match. This won't catch incorrect data
types that have the same size as the correct type, but will at least
avoid potential crashes.
