Use c-ts-common-statement-offset for closing brackets too

Merge c-ts-mode--close-bracket-offset into
c-ts-common-statement-offset.

* lisp/progmodes/c-ts-common.el:
(c-ts-common-statement-offset): Handle closing brackets too.
(c-ts-mode--close-bracket-offset): Remove function.
* lisp/progmodes/c-ts-mode.el (c-ts-mode--indent-styles): Use
c-ts-common-statement-offset for closing brackets.
