Add two at() functions that return mutable pointer to child nodes, based
on an index for lists and a key for dictionaries.
The API differs from const children accessors that use operator[] and
return a reference in order to allow better error handling: while the
const accessors return a reference to a global instance of an empty
ValueNode when the requested child doesn't exist, a mutable accessor
can't do the same without allowing modifying the empty global instance.

Plumb in the MaliC55 pipeline handler support for capturing frames

Introduce a data flow which uses the CRU to feed the ISP through

In detail:
- push incoming request to a pending queue until a buffer from the CRU
is available
- delay the call to ipa_->fillParams() to the CRU buffer ready event
- once the IPA has computed parameters feed the ISP through the IVC
with buffers from the CRU, params and statistics
- Handle completion of in-flight requests: in m2m mode buffers are
queued earlier to the ISP capture devices. If the camera is stopped
these buffers are returned earlier in error state: complete the
Request bypassing the IPA operations
- As cancelled Requests might now be completed earlier then IPA events,

The IPAManager is currently instantiated when constructing the
CameraManager constructor, in the CameraManager::Private constructor.
This is the only sizeable object constructed with the CameraManager, all
other components are constructed when starting the manager.
Early construction of the IPAManager isn't wrong per-se, but prevents
accessing the CameraManager from the IPAManager constructor (as the
former isn't fully constructed). It also results in internal objects
constructed in different threads, which isn't an issue at the moment as
none of the objects constructed by the IPAManager are thread-bound, but
could cause issues later. Finally, it prevents influencing the
IPAManager creation with parameters passed to the CameraManager::start()
function once we implement this, which would be useful for applications
to override configuration parameters related to IPA modules.
Move the instantiation of the IPAManager to start time to fix all those
issues.

The ipa_interface unit test uses a FIFO to communicate with the vimc IPA
module. FIFOs are named pipes, created in the file system. The path to
the FIFO is hardcoded so that both the unit test and IPA module know
where to locate the file.
If the ipa_interface crashes for any reason, the FIFO will not be
removed, and subsequent usage of the vimc IPA module will hang when
trying to write to the FIFO in the IPA module.
Fix this by replacing the FIFO with a pipe. Pipes are unidirectional
data channels that are represented by a pair of file descriptors,
without any presence in the file system. The write end of the pipe is
passed to the vimc IPA module init() function, and then used the same
way as the FIFO.
While at it, use a std::unique_ptr to manage the notifier in the unit
test instead of manually allocating and deleting the object.

Additionally, in raw capture mode, no parameter or statistics buffers are
