SpinBox is missing context_menu_enabled property

[h0lley]

Tested versions

v4.2.2.stable.official [15073af]

System information

Ubuntu

Issue description

LineEdit comes with a context_menu_enabled property that allows the user to disable the right-click context menu.

SpinBox also does have a right-click context menu but appears to be missing the corresponding option to disable it.

I am currently working on a project where right-click context menu must be disabled as they'd cause issues.

Steps to reproduce

See issue description.

You can control this by setting it on the embedded LineEdit with get_line_edit
