Replace usage of GlSegmentedControl with vue_shared component

In gitlab-ui#1787 (closed) we want to move vue_shared/... segmented_control_button_group component to GitLab UI. However, there is still a deprecated GlSegmentedControl in GitLab UI: &7261 (closed)

When moving vue_shared/... segmented_control_button_group, we want to override the existing deprecated GlSegmentedControl. However, the deprecated component is still used 1x in GitLab.

Task of this issue is to replace with first with the vue_shared component, to then work on gitlab-ui#1787 (closed)
