doc: Document the -folding option for -fdump-tree-* [PR114892]

I noticed that the -fdump-tree-*-folding flag isn't documented in
the Developer options section of invoke.texi; this patch fixes that.

gcc/ChangeLog:

	PR tree-optimization/114892
	* doc/invoke.texi (Developer Options): Document -folding option
	for -fdump-tree-*.
