Add "Copy link" action to groups menu

Feedback on the first iteration was that "Copy link" was ambiguous. Add
the term "invite" or "activity" to the label to indicate what the link
is for, depending on whether it is a group that the user can join or
not.

Replace references to old groups menu styles in new component

Update icon for "New private group" menu item

Update to latest icon from https://hypothicons.netlify.com.

Add an action to provide a convenient way to copy the sharing link
directly from the groups menu.

Depending on whether the group is private or open and whether the
receiving user is a member or not, the link may present the user with a
Join page or the activity page for the group. To simplify the client logic, the
text just says "Copy link".

I evaluated popular npm packages for this purpose (eg. [1]) but encountered
issues where they were not transpiled for use in older browsers or
included workarounds for browsers we no longer support (eg. IE 9).

If we do decide to use an existing package in future, we can keep this
utility module as a wrapper around it.

This replaces some references to the styles for the old groups menu in
the new implementation. The menu label is now slightly darker as it
uses the same grey as the menu items. Otherwise there should be no
noticeable visual changes.

The CSS itself has been simplified compared to the previous
implementation.

Update group menu styles

This enables consumers to use `&&` or `||` conditionals to compute the
`icon` prop.

Convert `<search-input>` component to Preact

 - {show, hide} => {renders, doesn't render} to clarify that we're
   checking whether an element is rendered at all, as opposed to merely
   visually hidden
 - Replace ambiguous GitHub issue reference with URL

This makes it easier to see when a submenu item is hovered.

 - Use the string "blank" instead of `null` as a more explicit indicator
   that a menu item should show a blank space for an icon
 - Rename two variables to indicate their boolean-ness

The icon is from the Hypothicons set at https://hypothicons.netlify.com

Following a design review, adjust the styling of menus and in particular the
groups menu to better match the mocks [1] and create better separation between
different elements.

- Add a 10px margin below section headers
- Add a subtle border at bottom of expanded submenus
- Remove red hover color for menu items
- Make submenu items slightly lighter and darken them on hover
- Reduce font size to match top bar and reduce font weight for submenu items
- Increase submenu toggle caret size slightly (10 => 12px) and darken
  the caret on hover, consistent with the effect when submenu items are
  hovered.
- Avoid hyphenating messages in the footer of group list submenus

Bump focus-visible from 4.1.5 to 5.0.0

Bump @octokit/rest from 16.28.0 to 16.28.2

 - Remove `@import` commands which duplicated SASS imports elsewhere in
   the bundle
 - Remove `:focus` selector which had no effect
 - Remove an unnecessary `@at-root` block which was used to contain a
   variable that was only used in one place and replace that usage with
   a constant instead

 - Rename `simple-search.scss` and the CSS classes it defines to match
   the name of the module which defines the component structure and
   logic
 - Remove reference to `simple-search-inactive` CSS class which did not
   exist

Merge pull request #1176 from hypothesis/dependabot/npm_and_yarn/babel-plugin-transform-async-to-promises-0.8.12

Bump babel-plugin-transform-async-to-promises from 0.8.11 to 0.8.12

Bump enzyme-adapter-preact-pure from 1.13.4 to 2.0.0

This test happened to pass before, but failed after an adapter upgrade.
All external state changes should be wrapped in `act` to flush state
updates and effects and followed by `wrapper.update` to update the
Enzyme adapter.

Convert loading spinner to Preact

Remove passing of search

Previously a search object was built inside the hypothesis-app
component and passed down to its child components. Now, just use
the store.getState().filterQuery directly. This avoids unnecessarily
passing things between components and a layer of indirection between
the search object and the value in the store. Rename searchQuery to
filterQuery.
