As part of comparing Vue search with legacy search, we need to track how
long it takes to lazy load the wvui library. A similar metric was added
to measuring the mediawiki.searchSuggest module in
I0fa6b8904bd43c87a68e9161f00d686a0e588966.
This commit adds the following metrics which will only be used in our
synthetic tests. We are not doing RUM tests at this time.
To test locally, add the following to your LocalSettings.php and append
the query param `useskinversion=2` e.g.
(http://localhost:8181/wiki/Test?useskinversion=2):
```
$wgVectorUseCoreSearch = false;
```
Marks:
* mwVectorVueSearchLoadStart: Marks the start of loading the search
module.
* mwVectorVueSearchLoadEnd: Marks the end of loading the search
module.
Measures:
* mwVectorVueSearchLoadStartToLoadEnd: Measures the time it takes to
load the search module.

Provides a loading indicator to show while the new Vue.js based
search widget loads. Given that the new widget will pull down the
entire Vue.js runtime, it's likely that there will be a delay
before the search suggestions appear. This loader is meant to
improve the perceived loading experience of the new widget.
Adds:
- New searchLoader.js file containing loading behaviour.
- This overrides the code searchSuggest loading behaviour.
- New SearchBoxLoader.less file containing the loader styles.
- i18n message: 'vector-search-loader'.
- The Event type to jsdoc.json
