Use `AnnotationHeader` directly

The issue has been fixed upstream, but we need to keep the workaround
for old versions of PDF.js with Hypothesis embedded, that still exist on
various websites.

This comment was written prior to the change to draw highlights in an
SVG in PDFs.

Remove obsolete fallback for browsers that don't support mix-blend-mode.
All of our current targets do, per https://caniuse.com/mdn-css_properties_mix-blend-mode.

These are no longer needed as the visual highlights in PDFs are now
created by SVG elements above the canvas, rather than by a background
color in PDF.js's text layer.

Removing these overrides fixes a cosmetic issue where overlapping text
boxes in the selection layer could create different shades of blue (or
whatever the selection color is) instead of blending into one, as shown
in https://github.com/hypothesis/private-issues/issues/108#issuecomment-1115392598.

Simplify the `watch` utility by making it only support a single callback to get
the watched value, along with an optional comparison function to use to compare
the results. To watch multiple values the callback can return an array and use a
shallow-equality comparison.

In `FrameSyncService` the lengthy callback passed to `watch` was
extracted into a separate function to make the `watch` call more
readable.

Feature flags are now sent to the host frame, which never changes, so
there is no point in re-sending flags when guest frames change. In
future we'll need to figure out how to communicate feature flags to
guest frames and depending on whether the sidebar or host frame does
this, the sidebar may once again need to react to guest frames changing.

- Make search icon alignment correct when input field is focused
- Add a mostly-opaque background so that collisions with long group
  names are less jarring
- Add a border when query applied but input not focused to make it
  more visible
- Use `TextInput` for more consistent focus-ring treatment
- Fix focus-ring overlap when input is visible

- Convert `LaunchErrorPanel`
- Convert `SidebarContentError`
- Convert `SortMenu`
