For some users, GetKeyboardLayoutNameA() returns an alias instead of the
fully resolved keyboard layout identifier. In that case, we have to
query the registry to resolve the alias before we can look up the DLL
path.

Contrary to what you can read on the internet, SGCAPS keys don't work
by having capslock toggle the KBDCTRL bit, they actually have two
consecutive table entries, the first of which is for the normal
version and the second of which is for the capslocked version.
Background: SGCAPS is short for Swiss German caps because Swiss German
was the first layout to use this feature. For keys with the SGCAPS flag,
capslock has a different effect than pressing shift. For example:
Shift + ü = è, CapsLock + ü = Ü, CapsLock + Shift + ü = È
DLL loading failures should not happen under normal circumstances, but
we should at least try not to crash and and print better diagnostic
messages if they do happen.

Previously, we treated CapsLock and KanaLock as part of the global
keyboard state, much like NumLock and ScrollLock, rather than using
the supplied modifier mask. This was because GDK does not have a
modifier mask for KanaLock, only for CapsLock, so it would not have been
possible to properly support it.
However, this approach ended up causing problems, with certain keyboard
shortcuts not registering when capslock was active. This was first
observed in Inkscape [0] and appears to affect shortcuts consisting of a
single key (like 'a') with no additional modifiers (wheareas shortcuts
like 'ctrl+a' work).
So now we are using the supplied GDK_LOCK_MASK instead, and dropped
support for KanaLock, which we probably don't need anyway (since regular
text input should be handled by the IME input module -- the keymap is
mainly for shortcuts and keybindings, where you don't really want
KanaLock).

The old code used repeated calls to `ToUnicodeEx` to populate
the translation table, which is slow and buggy. The new code
directly loads the layout driver DLLs from Windows.

Unref private spool_io of GtkPrintJob before setting it to a new one
in gtk_print_job_set_source_file() and gtk_print_job_set_source_fd()
to prevent a leak.

We are no longer using PangoFT2 APIs in this demo, so make sure that we build
it on all builds since we already depend on a HarfBuzz/Pango version that
provide everything that we need here.
Drop the unnecessary pangofc-font.h include as a result.
Like what was done on gtk/language-names.c, acquire the language names via the
native Windows NLS APIs, eliminating a run-time dependency on iso-codes on
Windows.
Instead of relying on the iso-codes package, use the native Windows NLS APIs to
acquire the localized (translated) language names so that we do not need to
incur an extra runtime dependency on Windows. It's not coverering 100% of the
languages that we would like to support through this, but should cover much of
the things that are required.
We aren't really using PangoFT2 for [language|script]-names.c, and are
always using items from them, so make sure they are being built.
Also always include the pangoft2 dependency in gtk_dep if it is found.
We were handling events in the wrong order,
by doing async calls for some of them, but not
for all of them.
And we were not taking into account that GFileMonitors
RENAMED events may or may not move a file on top
of an existing file.

Document the return value and more importantly, specify that a call to
`gsk_renderer_realize()` needs to be matched with a call
`gsk_renderer_unrealize()`.

Without building the demos, nothing gets installed into $prefix/share/icons/hicolor. Which makes running
`gtk4-update-icon-cache` on the machine causes an error. This is easily reproducible on a Windows machine with MSVC where
there is nothing pre-installed on hicolor icon theme and that makes building gtk without the demos fails with "No such file or directory".
