Add slot support to form builder radio and checkbox components

What does this MR do and why?

Related to #362013 (closed)

I have noticed when migrating checkboxes to use gitlab_ui_checkbox_component sometimes the checkbox requires HTML in the label or help text. With the current implementation you have to use sprintf to create a string and then pass it to the label or help_text argument. This MR utilizes ViewComponent slots to make using HTML in the label or help text easier and cleaner. This MR also gives the same treatment to gitlab_ui_radio_component.

Before

- label = _('Allow projects within this group to use Git LFS')
- help_link = link_to sprite_icon('question-o'), help_page_path('topics/git/lfs/index'), class: 'gl-ml-2'
= f.gitlab_ui_checkbox_component :lfs_enabled,
  '%{label}%{help_link}'.html_safe % { label: label, help_link: help_link },
  help_text: _('This setting can be overridden in each project.'),
  checkbox_options: { checked: @group.lfs_enabled? }

After

= f.gitlab_ui_checkbox_component :lfs_enabled, checkbox_options: { checked: @group.lfs_enabled? } do |c|
  = c.label do
    = _('Allow projects within this group to use Git LFS')
    = link_to sprite_icon('question-o'), help_page_path('topics/git/lfs/index'), class: 'gl-ml-2'
  = c.help_text do
    = _('This setting can be overridden in each project.')

To demonstrate how this update works I updated an instance of a checkbox and an instance of a radio button. See screenshots below.
