Load the signature from the .sign file, if available, when loading the
IPA module information and store it in the IPAModule class.

Switch IPA communication to the plain C API. As the IPAInterface class
is easier to use for pipeline handlers than a plain C API, retain it and
add an IPAContextWrapper that translate between the C++ and the C APIs.
On the IPA module side usage of IPAInterface may be desired for IPAs
implemented in C++ that want to link to libcamera. For those IPAs, a new
IPAInterfaceWrapper helper class is introduced to wrap the IPAInterface
implemented internally by the IPA module into an ipa_context,
ipa_context_ops and ipa_callback_ops.

The ipa includes are located in include/libcamera/ipa/. This gives an
incorrect impression that they are a sub-part of the rest of the
libcamera API, while they are the API towards the IPA the same way that
include/libcamera/ contains the API towards applications. To clarify
this, move them to include/ipa/.
The IPA headers are however still part of libcamera, so installing them
to ${prefix}/include/ipa/ would make little sense. To fix this, move the
application facing API to ${prefix}/include/libcamera/libcamera/ when
installed, and the IPA to ${prefix}/include/libcamera/ipa/. When major
versions of libcamera will be released, they could then be installed
side by side in ${prefix}/include/libcamera-${version}/.

Add a method to IPAModule to check if the module is open source.
This uses the license field of the member IPAModuleInfo.

Add functions for loading the IPAInterface factory function from an IPA
module shared object, and for creating an instance of an IPAInterface.
These functions will be used by IPAManager, from which a PipelineHandler
will request an IPAInterface.
Also update meson to add the "-ldl" linker argument, to allow loading of
the factory function from a shared object.

Implement a class to wrap around an IPA module shared object.
For now, just load a struct IPAModuleInfo with symbol name
ipaModuleInfo from an IPA module .so shared object.
Also provide a public header file including the struct IPAModuleInfo,
structured such that both C and C++ IPA modules are supported.
