declare -c to capitalize first character of string in variable

Thanks for the reminder. I keep forgetting to turn this off. It's too late
for bash-5.1, but I have it tagged to flip to disabled by default in
config-top.h in bash-5.2.
    It is replaced with something else?

There's nothing to directly replace `declare -c', which was a bad idea to
begin with. You can use the new @u parameter transformation operator to
replace ${v~}. The ability to use the pattern in @{v~[pattern]} wasn't a
great idea either.
