The "Add parameter" page always starts collapsed. Even if a template
doesn't contain anything but this. But most of the content isn't
visible, unless the user presses the button. It's not only a lot of
content, it's also rather expensive, including .parseDom(),
LinkCache.styleElement(), and ve.targetLinksToNewWindow(). This adds
up in large multi-part transclusions. In an example with 200 parts
the total blocking time goes down from 2.9s to 2.4s. Which means this
is not a major bottleneck, but still worth it.
Bug: T296335

This patch improves the error handling for when a user tries to add
a parameter which is either an alias of a existing parameter, the
primary name of a existing aliased parameter, or a name/alias of an
existing parameter which is shown with an override label.
The error message was modified to always refer to the conflicting
parameter using the same name that is has in the sidebar.
Example: A parameter named "Parameter B" is already present in the
sidebar under its alias "B". When a user tries to add "Parameter B",
the new error message will inform the user that the parameter they
are trying to add already exists as "B".

This is split from patch Iebb982e to make it easier to review.
The name is rather ambiguous. Does "input" refer to the input
element? Is it triggered for every key press, i.e. when the
input changes? Or when it's submitted?
