The resource compiler in the Windows 11 SDK does not allow one to include
winuser.h directly in resource scripts (.rc) with a rather cryptic error
message, so fix generating the .rc file to embed the UAC manifest by including
windows.h with WIN32_LEAN_AND_MEAN instead.
The installed ITS rule filename is "gtk4builder.its". The .loc file
is wrongly pointing to old "gtkbuilder.its" which makes gettext fail
on systems without GTK3 installed.
Not sure we can do much with a ui file that has
<placeholder/> elements littered throughout. But
at least we can avoid crashing while trying to
convert it.
Fixes: #3781
As the program executable name has 'update' in its filename,
gtk4-update-icon-cache.exe is considered to be an installer program on 32-bit
Windows [1], which will cause the program to fail to run unless it is running
with elevated privileges (i.e. UAC).
Avoid this situation by embedding a manifest file into the final executable
that tells Windows that this is not a program that requires elevation.
Fixes issue #3632.
