b318101ada libcamera: ipa: Drop unneded includes from ipa_interface.h
The ipa_interface.h file includes a number of headers that are not
directly used. Remove them, and add them to the source files that
include ipa_interface.h as required.

0e333755ff utils: ipc: Include <string> in generated headers where needed
Depending on the types used in the IPA interface, generated headers may
use the std::string class. Include <string> when needed.

5c1cb5e5bc py: gen-py-controls: Use Control class
Replace manual extraction of data from YAML with the Control helper
class. This centralizes YAML parsing and avoids manual mistakes.

In order to import the controls module, add the utils/codegen/ directory
to the PYTHONPATH through the Python build environment.

6a96113107 utils: codegen: gen-controls.py: Move helper classes to separate file
The ControlEnum and Control helper classes defined in gen-controls.py
are useful for other generator scripts. Move them to a separate file to
make it possible to share them.

dc067c4bce utils: codegen: gen-controls.py: Convert to jinja2 templates
Jinja2 templates help separate the logic related to the template from
the generation of the data. The python code becomes much clearer as a
result.

As an added bonus, we can use a single template file for both controls
and properties.

48f9660acd utils: codegen: gen-header.sh: Generate libcamera.h based on meson.build
The libcamera.h header is a top-level library header that contains every
other libcamera header. It is currently generated by listing the files
in include/libcamera/ and dropping the .in suffix from template files.
This assumes a 1:1 mapping between generated header file names and the
name of their templates.

Drop that assumption and base the libcamera.h generation on the
libcamera public headers listed in meson.build. This makes the
libcamera.h header generation more future-proof.

a5f12d2eb3 meson: utils: Provide environment for Python scripts
Python scripts run as part of the build process need to take a few
actions specific to the environment in which they operate. One of those
is disabling the Python bytecode cache, to avoid writing .pyc files to
the source tree. This is done manually in the IPC generate.py and
parser.py scripts.

The current implementation is not ideal because it hardcodes in the
scripts information related to the environment in which they operate. As
those scripts are part of libcamera this is more of a theoretical issue
than a practical one. A second issue is that future Python scripts will
need to duplicate similar mechanisms, resulting in a higher maintenance
burden.

Address the issue with a different approach, by creating a meson
environment for the Python scripts, and passing it to the
custom_target() functions. The environment only disables the bytecode
cache for now.

The diffstat shows an increase in code size. This is expected to be
offset by usage of the environment for more Python scripts, as well as
support of more variables in the environment.

50c92cc7e2 meson: Move all code generation scripts to utils/codegen/
We have multiple code generation scripts in utils/, mixed with other
miscellaneous utilities, as well as a larger code base based on mojom in
utils/ipc/. To make code sharing easier between the generator scripts,
without creating a mess in the utils/ directory, move all the code
generation code to utils/codegen/.
