Meson uses tags to sort installed files in categories, and makes it
possible to install a subset of the files using the '--tags' argument to
'meson install'. This is typically used by distributions to split the
runtime, development and documentation files into separate packages.
By default, meson tries to guess the correct tag for installed files,
but can't always do so properly. Mark the install targets that meson
can't guess with the correct install_tag.
As the feature has been introduced in meson 0.60, bump the minimum meson
version. The latest LTS release of all major distributions that
libcamera currently targets ship a recent enough meson version.

Add a '--orientation|-o' option to the cam test application to set
an orientation to the image stream.
Supported values are the ones obtained by applying flips to the camera
sensor:
- rot0: no rotation
- rot180: rotate 180 degrees
- flip: vertical flip
- mirror: horizontal flip

When packaging libcamera, distributions may break IPA module signatures
if the packaging process strips binaries. This can be fixed by resigning
the modules, but the process is error-prone.
Add a command line ipa-verify utility that tests the signature on an IPA
module to help packagers. The tool takes a single argument, the path to
an IPA module shared object, and expects the signature file (.sign) to
be in the same directory.
In order to access the public key needed for signature verification, add
a static function to the IPAManager class. As the class is internal to
libcamera, this doesn't affect the public API.

Now that `Camera::generateConfiguration()` takes a `libcamera::Span`
of `StreamRole`, remove the `StreamRoles` type, which was an alias
to `std::vector<libcamera::StreamRole>`.
The removal has two reasons:
- it is no longer strictly necessary,
- its presence may suggest that that is the preferred (or correct)
way to build/pass a list of `StreamRole`.

A new warning has been introduced to gcc-13 that produces a false
positive on the cam file sink object:
src/cam/file_sink.cpp:92:45: error: possibly dangling reference to a temporary [-Werror=dangling-reference]
92 | const FrameMetadata::Plane &meta = buffer->metadata().planes()[i];

92 | const FrameMetadata::Plane &meta = buffer->metadata().planes()[i];

cc1plus: all warnings being treated as errors
Workaround this issue by refactoring the code to take a local const
copy of the bytesused value, rather than a local const reference to the
plane.

In the simple capture tests, in the capture functions, the Requests were
auto-deallocated by the function going out of scope after the test
completed. However, before the end of the scope, the Framebuffers that
the Requests referred to were manually freed. Thus when the Requests
were deallocated, they tried to cancel their Framebuffers, which involve
setting the status to cancelled, which obviously causes a segfault
because the Framebuffers had already been freed.
Fix this by moving the list of Requests to a member variable and
deallocating them before deallocating the Framebuffers at stop() time.
