Merge in NSI presets after UI has initialized

Added a deferred work queue to do this with requestIdleCallback in the background

This means less work for the other parts of the code,
now they don't need to chain that extra step after the promise.

(should have been in 868db88)

This also fixes the logic for calculating whether the preset shows a
`brand` or `operator` field - it needs to use `fields()` to actually
resolve the fields, as these fields can be inherited from another preset.

This also includes a change to match "primary" names before
"alternate" names (aka the "Baby Gap" / "Gap" problem)

- implements a validation work queue, jobs are run during browser idle callbacks
- when merging base entities, don't run validations 2x on both base and head graphs (this was wasteful)
- keep track of resolved issues in a separate set (it's not a simple compare of base/head anymore)
  this happens after validation queue is empty and avoids race conditions and inaccurate resolved counts

Also add a ton of commments to validator.js

Promisify validation

- don't try matching semicolon-separated lists to NSI
- better matching for flagpoles with a `country` tag
- better lists of namelike keys (don't match flag operator)

osmEntity#hasWikipedia was only used by the suspicious_name validator

This has caused problems going back a long time, and now that we have a validator
and very visible brand presets with logos, it's not necessary anymore.

This involves a few things to make the validator less weird
- _headGraph shouldn't be allowed to change while validation is happening..
- So we don't allow that to happen anymore, and keep track of _headPromise and _headIsCurrent
- If head graph falls behind, kick off another validation to catch it up
- Separate head and base work queues, so we aren't waiting for the base entities to validate
  before providing feedback to the user about what they are editing
  (the base queue can get quite large around metropolitan areas)

visibility:hidden still preserves space, which would uncenter the image in some cases

- Actually bail out properly if namelike values contain semicolon ';'
- Prioritize the canonical tags like `brand:wikidata`, `operator:wikidata`
- Don't insert a name into 'alternate' set if it's already in 'primary' set

Includes the feature type in the label
(re: osmlab/name-suggestion-index#4543 (comment))

This shows the tag diff, and other helpful information about the detected issues.
It is expanded by default now

Needed this after I added `highway=bus_stop` to the transit tree

This is for "nextbike"

The lack of locationSet was causing them to not show up, which indirectly
broke the tutorial at the step where user needs to pick the road category.

This simplifies the code a bit, just treat it as worldwide if missing

This now breaks the name into fragments and reruns the fragments against the NSi matcher
rather than using flaky regular expressions. Has a few advantages:

Also bump country-coder and location-conflation
