kbuild: Use if_changed for font and splash .incbin rules
The generated .S files for fonts and splash screens use .incbin with the
full prerequisite path. When building with O= this bakes an absolute
path into the .S file. If the build directory is later used on a
different machine (e.g. in a container), the assembler cannot find the
source file.
Follow the existing DTB convention: rename the object targets to use
compound suffixes (.ttf.o, .bmp.o), switch the pattern rules from
direct $(call cmd,...) to FORCE + $(call if_changed,...), and register
the new suffixes with intermediate_targets so that kbuild loads their
.cmd files. This lets if_changed detect when the recorded command
(including source paths) has changed and regenerate the .S file
automatically.
The EFI rule is left unchanged since its prerequisite is a generated
file in the build directory, like the DTB and DTBO rules.
The intermediate_targets entries stay in scripts/Makefile.build rather
than moving to scripts/Makefile.lib-u-boot, because that file is
included before intermediate_targets is defined and 'targets' is ':=',
so a '$(call intermediate_targets, ...)' inside it would expand to
empty and silently drop the entries. To keep the upstream block
untouched, the U-Boot additions go in a separate 'targets +=' block
immediately below.
