Moving the core.mojom documentation to its corresponding .cpp file
(core_ipa_interface.cpp). This will allow Doxygen to generate the
documentation for IPABuffer, IPASettings and IPAStream structures.
Since the .mojom files are placed in include/ directory, the .cpp file
will live in $sourcedir/src/libcamera/ipa/ - which can also contain
documentation for other mojom generated IPA interfaces in subsequent
commit.
Also hide the constructors in generated IPA interface from doxygen,
via #ifndef __DOXYGEN__. These constructors provide no major value in
documenting them, instead will spew out doxygen warnings during the
build.

Structs defined in mojom previously used the namespace of the mojom file
that was being used as the source. This is obviously not the correct
namespace for structs that are defined in core.mojom. Fix the jinja
function for getting the element type including namespace, and use it.

Asynchronous tasks can only be submitted while the IPA is running.
Further more, the shutdown sequence can not be tracked with a simple
running flag. We can also be in the state 'Stopping' where we have not
yet completed all events, but we must not commence anything new.
Refactor the running_ boolean into a stateful enum to track this.

Events may be queued to the pipeline handler between the pipeline
handler entering the ::stop() function, and before the call to stop the
IPA has completed.
Handle these events by dispatching all pending messages at the proxy
after the IPA has fully stopped.

Signals and calls from the IPA should not occur after the IPA has been
put into the stopped state.
Add assertions to catch and prevent any messages being processed after
this.

To make it more convenient for synchronous IPA calls to return a status,
convert the first output into a direct return if it is an int32.

Add support to the mojom-based code generator for custom parameters to
init(). Remove the parameter type and count validation as well.

Add templates to mojo to generate code for the IPC mechanism. These
templates generate:
- module header
- module serializer
- IPA proxy cpp, header, and worker
Given an input data definition mojom file for a pipeline.
