Throw an exception when gr-app.html cannot be used to locate the
JS path root. Handle the case where HLJS is independently loaded.

This is a partial roll-forward of c/106190
This replaces all loads of iron-test-helpers with a load of a file
that wraps it, and adds that file to test files that do not currently
load iron-test-helpers.
A future CL will also install polymer-resin via common-test-helpers.html.
I tested by running
$ WCT_ARGS="-l chrome" ./polygerrit-ui/app/run_test.sh

polymer-resin intercepts polymer property assignments
before they reach XSS-vulnerable sinks like `href="..."`
and text nodes in `<script>` elements.
This follows the instructions in WORKSPACE for adding a new bower
dependency with kaspern's tweak to use the dependency in a rule so
that it's found. //lib/js/bower_components.bzl has already been
rolled-back per those instructions.
The license is the polymer license as can be seen at
https://github.com/Polymer/polymer-resin/blob/master/LICENSE though
I'm not sure that //tools/js/bower2bazel.py recognizes it as such.
Docs for the added component are available at
https://github.com/Polymer/polymer-resin/blob/master/README.mdhttps://github.com/Polymer/polymer-resin/blob/master/getting-started.md
With this change, when I introduce an XSS vulnerability as below,
polymer-resin intercepts and stops it.
Patch that introduces a strawman vulnerability.

Load polymer-resin into polygerrit-ui/**/*_test.html
After this, I ran the tests with
-l chrome
-l firefox
I ran a handful of tests with -p and observed that the
console shows "initResin" is called before test cases start
executing.
These changes were done programmaticly by running the script below
(approximately) thus:
```
gerrit/ $ cd polygerrit-ui/app
app/ $ find . -name \*test.html | xargs perl hack-tests.pl
```
```
use strict;
sub removeResin($) {
my $s = $_[0];
$s =~ s@<link rel="import" href="[^"]*/polymer-resin/[^"]*"[^>]*>\n?@@;
$s =~ s@<script src="[^"]*/polymer-resin/[^"]*"></script>\n?@@;
$s =~ s@<script>\s*security\.polymer_resin.*?</script>\n?@@s;
return $s;
}
for my $f (@ARGV) {
next if $f =~ m@/bower_components/|/node_modules/@;
system('git', 'checkout', $f);
print "$f\n";
my @lines = ();
open(IN, "<$f") or die "$f: $!";
my $maxLineOfMatch = 0;

update Soy index template to new style polymer-resin initialization

fix lint warnings

Load test/common-test-setup.html into *_test.html
Instead of inserting instructions to load and initialize polymer-resin into
every test file, add a common-test-setup.html that does that and also fold
iron-test-helpers loading into it.

imported files do not need to load webcomponentsjs

Tapping the "Show Diffs" link in the change view to display all of a
change's diffs inline spawns several asynchronous syntax highlighting
processes. Sometimes (especially for long file lists and slower HLJS
download rates) multiple highlight processes would request HLJS before
it had been loaded, resulting in multiple load/definitions of the
library. Occasionally this would result in a JS exception.
With this change, the HLJS loader functionality of GR-SYNTAX-LAYER is
separated into the GR-SYNTAX-LIB-LOADER component. This component
employs a singleton property to track state across multiple lib requests
behind a promise interface.
Tests are updated.
