Use meson's files() to list the mojom files instead of the file names
directly. This is so that we can still access the files from
src/libcamera/ipa/meson.build later for building documentation cpp
files from the mojom files.
While at it, fix some redundant string manipulation in building the
mojom modules.

The addition of the new IPA IPC mechanism compiles pipeline-specific
headers to define the interface between the pipeline and the IPA.
This was optimised in 08ce394465 ("meson: ipa, proxy: Only build
proxies for enabled pipelines") to only build for enabled pipelines,
however the tests directly use the VIMC pipeline handler, and require
it to be built.
Create a local variable to store the requested pipelines from the user
configuration and extend the enabled pipelines to ensure that VIMC is
always enabled if the tests are also enabled

Remove everything related to the C API, including ipa_context,
ipa_context_wrapper, and IPAInterfaceWrapper. Also remove relevant
documentation.
ipaCreate() provided by IPA implementations, and createInterface()
provided by IPAModule (wrapper around IPA implementation) both now
return a C++ object IPAInterface instead of struct ipa_context.
Although IPAInterfaceWrapper is the only component of libipa, the
skeleton and build files for libipa are retained.
After converting the C API to the C++-only API, make all pipeline
handlers and IPAs use the new API.

libcamera: IPAProxy, IPAManager: Switch to one-proxy-per-pipeline scheme
IPAProxy is changed in two major ways:
- Every pipeline has its own proxy, to support each pipeline's IPA
interface
- IPAProxy implementations always encapsulate IPA modules, and switch
internally for isolation or threaded
The IPAProxy registration mechanism is removed, as each pipeline will
have its own proxy, so the pipeline can pass the specialized class name
of the IPAProxy to the IPAManager for construction.
IPAManager is changed accordingly to support these changes:
- createIPA is a template function that takes an IPAProxy class, and
always returns an IPAProxy
- IPAManager no longer decides on isolation, and simply creates an
IPAProxy instance while passing the isolation flag
Consequently, the old IPAProxy classes (IPAProxyThread and
IPAProxyLinux) are removed. The IPAInterfaceTest is updated to use
the new IPAManager interface, and to construct a ProcessManager as no
single global instance is created anymore.

libcamera: IPAProxy: Remove registration mechanism
Implementations of IPA proxies use a registration mechanism to register
themselves with the main IPA proxy factory. This registration declares
static objects, causing a risk of things being constructed before the
proper libcamera facilities are ready. Since each pipeline handler has
its own IPA proxy and knows the type, it isn't necessary to have a proxy
factory. Remove it to alleviate the risk of early construction.

The list of public, IPA and internal header files are stored in three

The IPA headers are installed into $prefix/include/libcamera/ipa/, but
are located in the source tree in include/ipa/. This requires files
within libcamera to include them with
#include <ipa/foo.h>
while a third party IPA would need to use
#include <libcamera/ipa/foo.h>
Not only is this inconsistent, it can create issues later if IPA headers
need to include each other, as the first form of include directive
wouldn't be valid once the headers are installed.
Fix the problem by moving the IPA headers to include/libcamera/ipa/.
