This adds the primary reactions to the action bar. They act as toggles where you
can only select one from each group at a time.
Note that currently we aren't actually sending the reaction at all. That's left
for a separate task.

This applies the new design for multiple buttons in the message action bar,
paving the way for more things to appear here.
In addition, this changes the existing options button to use the three vertical
dots icon. Some theme colors are also tweaked to align with what they were meant
to be from the unified palette.
This adds a new action bar component to hold multiple per-message actions. This
existing options button has moved to this new component, and is currently the
only action.
Text colour ended up being the link colour on images because the
whole image is in an `a`, but stickers are not so it got the default
font colour, which might be black. Define an explicit colour.
Also set pointer-events: none so you can hover over the gif icon
too (I managed to make the message panel small which made the icon
cover most the image, so this prevented the gif from animating
at all).

The benefits of this:
- One code path for determining spinner/placeholder and it's position
for loading images/stickers. This includes spinner used in e2e
decryption of images.
- Very small definition for MStickerBody, only overriding the minimal
differences is has from MImageBody.
The disadvantages:
- Slightly more complicated MImageBody, but hopefully not less
readable.
As the slightly nicer alternative to fixupHeight being applied once
we actually have a timelineWidth.
The niceness comes from not needing timelineWidth, which means we can
implement at render time with CSS. (Despite still calculating aspect
ratios when we render.)
