gen-evolution.awk was explicitly blacklisted
and so was gen-cxxapi-file.py, both because update-copyright.py
matched Copyright line also within the printing code but it wasn't
matching the expected form.
Fixed by making sure the printing code doesn't match it by using
print "   Copy" "right (C) " ... in the awk case and
Copy{:s}right in the python case (with "" arg added).

contrib/
	* update-copyright.py (GCCFilter): Don't filter out
	gen-evolution.awk and gen-cxxapi-file.py.
gcc/
	* config/loongarch/genopts/gen-evolution.awk: Update
	copyright year.
	(copyright_header): Separate parts of Copyright word
	with " " so that it doesn't get matched by update-copyright.py.
	(gen_full_header, gen_full_source, gen_full_def): Include
	2026 year in the ranges.
gcc/cp/
	* gen-cxxapi-file.py: Update copyright year.  Separate
	parts of Copyright word with {:s} so that it doesn't get matched
	by update-copyright.py.
