Commit "weston-log: add function to avoid direct
access to compositor members in non-core code" added the
function weston_compositor_add_log_scope mainly to allow
libweston users to avoid direct accessing core structs, as
weston_compositor.
Replace weston_log_context_add_log_scope usage by
weston_compositor_add_log_scope.

There's a function named weston_compositor_log_scope_destroy()
but it doesn't take a struct weston_compositor argument.
Rename it to weston_log_scope_destroy(), as the argument is a
struct weston_log_scope.

There's a function named weston_compositor_add_log_scope()
but it doesn't take a struct weston_compositor argument.
Rename it to weston_log_ctx_add_log_scope(), as
the log_scope is being added to a log_context.
Also, bump libweston_major to 9.

This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.
Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.
All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
did not fit there.
Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.
Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

As 'new_subscription' can create additional objects, 'destroy_subscription'
will be needed when cleaning up.
As this requires a libweston_major bump (noticed by @pq), bump it up to
8.

It is quite similar to the remoting plugin. It just exports the frames via
pipewire instead of the builtin GStreamer pipeline.
It implements the same virtual output API. Virtual outputs can be created
by adding 'pipewire-output' sections to weston.ini.
The generated frames can be accessed with any pipewire client. e.g. with
GStreamer:
gst-launch-1.0 pipewiresrc ! video/x-raw,format=BGRx ! ...
