Nicholas Ray 3aaedcfe3c [search] Add Vue search performance instrumentation
This is almost identical to the instrumentation currently used in
production for mediawiki.searchSuggest -- the only differences being in
the nomenclature of variables, etc.

As part of comparing Vue search with legacy search, we need to track how
long it takes a keypress to load and render search results for Vue
search. This will only be used only in synthetic testing at this time
(Real user monitoring (RUM) is not in scope for this ticket).

To test locally, first enter characters in input. Then to see the
metrics recorded:

```
// View all marks
performance.getEntriesByType('mark');

// View all measures
performance.getEntriesByType('measure');
```

This commit adds the following metrics which will only be used in our
synthetic tests. We are not collecting RUM metrics at this time.

Measures:

* mwVectorVueSearchLoadStartToFirstRender: Measures the time it takes
from the start of loading the search module to the first render of results.

* mwVectorVueSearchQueryToRender: Measures the time it takes from
the start of the fetch to the render of search results.
