ruby-method-params-indent: New user option

* lisp/progmodes/ruby-mode.el (ruby-method-params-indent):
New option (bug#60110).

(ruby-smie-rules): Use it.

* etc/NEWS: Mention it.

* test/lisp/progmodes/ruby-mode-resources/ruby.rb:
Ensure the var's value is default.

* test/lisp/progmodes/ruby-mode-resources/ruby-method-params-indent.rb:
New file.

* test/lisp/progmodes/ruby-mode-tests.el (ruby-deftest-indent):
New macro, use it to run the indentation test using the new file.
Disable the :expensive-test tag, because neither runs for "longer
than some few seconds", both take significantly below 1s.
