93e72b695e libcamera: Move internal headers to include/libcamera/internal/
The libcamera internal headers are located in src/libcamera/include/.
The directory is added to the compiler headers search path with a meson
include_directories() directive, and internal headers are included with
(e.g. for the internal semaphore.h header)

  #include "semaphore.h"

All was well, until libcxx decided to implement the C++20
synchronization library. The __threading_support header gained a

  #include <semaphore.h>

to include the pthread's semaphore support. As include_directories()
adds src/libcamera/include/ to the compiler search path with -I, the
internal semaphore.h is included instead of the pthread version.
Needless to say, the compiler isn't happy.

Three options have been considered to fix this issue:

- Use -iquote instead of -I. The -iquote option instructs gcc to only
  consider the header search path for headers included with the ""
  version. Meson unfortunately doesn't support this option.

- Rename the internal semaphore.h header. This was deemed to be the
  beginning of a long whack-a-mole game, where namespace clashes with
  system libraries would appear over time (possibly dependent on
  particular system configurations) and would need to be constantly
  fixed.

- Move the internal headers to another directory to create a unique
  namespace through path components. This causes lots of churn in all
  the existing source files through the all project.

The first option would be best, but isn't available to us due to missing
support in meson. Even if -iquote support was added, we would need to
fix the problem before a new version of meson containing the required
support would be released.

The third option is thus the only practical solution available. Bite the
bullet, and do it, moving headers to include/libcamera/internal/.

6e1cd1394e ipa: Name IPA modules after their source directory
The IPAModuleInfo::name field is currently a free-formed string that has
little use. Tighten its usage rules to make it suitable for building
file system paths to IPA-specific resources by matching the directory
name of the IPA module.

ebd0cae455 libcamera: ipa: Remove IPAModuleInfo license field
The IPAModuleInfo license field isn't needed anymore now that modules
are cryptographically signed. Remove it.

6f553040fd test: ipa: Fix path to VIMC IPA
When changing the VIMC IPA source file structure the path in the
ipa_module_test which needs access to the .so file was not updated, fix
that.

The omission was hard to spot as it requires a clean build of the
project as the old .so file is still in the build tree and the test
passes.

b999161b7d test: ipa: Rename the ipa_test to ipa_module_test
Update the IPA test to match the test class name in prevision of adding
more IPA tests. Also update the description comment in the test unit, as
the old name for the test was still used.
