C++ Mode: Fontify functions correctly with commas in template expressions

This fixes bug #57318.

Also apply an optimization which marks generic expressions as already
analyzed, thus avoiding repeating this analysis when not needed.  This
optimization prevents the fix slowing down scrolling when the C++ source has
lots of template structures.

expression also when the opening < is marked with a c-<>-c-types-set text
property.  Set this property at the same time as the c-type properties are set
on the commas inside the template structure.

* lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare): Clear the
c-<>-c-types-set text property, along with c-type, from the region being
fontified.

Fix describe-char-fold-equivalences for composed characters

* lisp/char-fold.el (describe-char-fold-equivalences): Map
`get-char-code-property' across all the component codepoints of the
equivalent character rather than just the first one.

; Fix the lispref manual about seq.el

preloaded, so no need to load it manually.  (Bug#57505)
