Building libcamera as a subproject is failing when tracepoints are
enabled due to incorrectly managing the relative paths between the
source and build directory while generating tracepoint headers.
The previously used
path = output.replace('include/', '', 1)
logic is not sufficient to correctly determine the proper path when
libcamera is built as a subproject, and does not correctly handle the
relative paths, causing path to be processed as:
'subprojects/libcamera/include/libcamera/internal/tracepoints.h'.replace('include/', '', 1)
which evaluates to
'subprojects/libcamera/libcamera/internal/tracepoints.h'
so the tracepoints.h header file will try to include:
#define TRACEPOINT_INCLUDE "subprojects/libcamera/libcamera/internal/tracepoints.h"
which will fail.
Fix it by using Python's pathlib to calculate the relative path of the
output file with respect to the "include" directory of libcamera.
This has been tested with Pipewire. For non-subproject builds it should
generate the exact same path that was previously generated.

The ControlList::set() function overload used for array controls
constructs a Span from an initializer list. It doesn't specify the Span
size explicitly, which results in a dynamic extent Span being
constructed. That causes a compilation failure for fixed-size array
controls, as they are defined as Control<T> with T being a fixed-extent
Span, and conversion from a dynamic-extent to fixed-extent Span when
calling ControlValue::set() can't be implicit.
Fix this by constructing the Span using the size of the control, which
resolves to a fixed-extent and dynamic-extent Span for fixed-size and
dynamic-size array controls respectively. The ControlList::set()
function that takes an initializer list can then be used for fixed-size
array controls.

The REGISTER_PIPELINE_HANDLER() macro defines a class type that inherits
from the PipelineHandlerFactory class, and implements a constructor and
a createInstance() function. Replace the code generation through macro
with the C++ equivalent, a class template, as done in libipa with the
Algorithm and CameraSensorHelper factories.

Avoid naked pointer with memory allocation by returning a unique_ptr
from PipelineHandlerFactory::createInstance(), in order to increase
memory allocation safety.
This allows iterating over factories in the CameraManager and unit tests
using const pointers.
