Convert markdown editor 3/3 - Convert editor and improve toolbar UX

Move the utility function to the top of the file so that all the
components are grouped together.

Also reformat `markdown-editor-test.js`.

 - Remove `user-select` rule. This is no longer needed because the
   toolbar buttons are `button` elements rather than `i` elements
   (which have selectable text)
 - Simplify border rules
 - Use CSS color name instead of a variable for consistency within the
   file

This has been replaced by the `MarkdownView` and `MarkdownEditor`
components.

Convert the editor part of the `<markdown>` component to Preact.

 - Remove the `readOnly` input as this mode is now handled by the
   separate `MarkdownView` component
 - Improve toolbar a11y by:
   - Adding the "toolbar" ARIA role and an aria-label to the toolbar container
   - Using `button` elements for toolbar buttons
   - Increasing the hit target area for buttons
 - Improve toolbar styling by:
   - Using flexbox
   - Using the modern color palette
   - Fixing the padding around the preview output

Convert markdown editor 2/3 - Convert markdown viewer

Convert markdown editor 1/3 - Remove "enabled" state from excerpt component

Convert the view mode of the markdown editor (when `readOnly` is `true`) to Preact.
The edit mode (when `readOnly` is `false`) will become a separate
component.

Simplify the `<excerpt>` component by removing the `enabled` property.
This property was used to avoid the markdown editor being truncated when
rendered inside the excerpt. However it is possible to achieve the same
result without this property by using `ng-if`.

This change will simplify porting the excerpt component to Preact and
also paves the way to splitting the existing `<markdown>` component into
two separate, simpler, components: One for the "view" mode and one for the "edit"
mode.

Enable throttling of concurrent builds

Jenkins CI builds of the client project are prone to failing when many
concurrent builds occur. This often happens when many Dependabot PRs are
submitted at once during a weekly dependency update. These builds
succeed most of the time when retried.

Limiting the number of concurrent builds per executor can be done globally,
but it can also be done on a per-project basis using the
throttle-concurrents [1] plugin. Assign a throttling category to client
builds so that this latter approach can be used.
