Display a warning when some images are missing, instead of crashing.
Also, don't keep old images around when loading a new set, and make use
of get_piece_graphic() more often.
Previously we would give up on loading the piece images if one fails.
That was awkward because 2 out of 3 places where `set_piece_set_name()`
is called can't propagate errors, so we'd just crash.
Instead, let's skip any images that fail to load, and then when painting
the preview, skip any missing bitmaps and show a warning message that
some are missing.
This will be required for propagating the current animation time to all
relevant timelines, which each propagate that time to all of their
relevant animations.
This does _NOT_ correspond to anything in the IDL or ECMAScript spec,
but is a custom extended attribute.
We use it to define the "enumerated" values of an attribute
Instead of a StringView. This allows us to preserve the nice O(1) string
compare property of FlyString, and not needing to allocate when one is
needed.
Ideally all other places in Token should have similar changes done, but
to prevent a huge amount of churn, just change ident for now.

Notable changes that affect us include:
* The Islamic Calendar is now localized as the Hijri Calender (in en-US)
but has not been updated for all locales. So this patch updates tests
where possible and removes a few test cases that currently cannot be
localized.
* The und locale has received more likely subtag data (the und locale is
basically a pseudo-locale meaning "undetermined").
* The exponential symbol in the Arabic number system was changed from
U+0627 to U+0623.
It's a little awkward that one caller of this is passing through an
Optional<String> and another an Optional<DeprecatedString>, but that
should be fixed some point in the future with further DeprecatedString
porting.
No IDL file pulls in these requiring DeprecatedString support, so we
are now able to remove these functions! :^)
Also leave a FIXME while we are at it, as ideally this function would
take an Optional<FlyString> - but the IDL generator does not currently
support this.
These were DeprecatedFlyStrings, but had no reason to be. We were not
making use of the O(1) lookup, so instead of porting it over to a
FlyString, just make it a StringView.
This is the API for NamedNodeMap which we are wanting to eventually use
instead of taking a StringView. Currently we just end up deferring to
the StringView versions of these functions, but at some stage in the
future, this will allow us to have O(1) comparison when making attribute
lookups.
In the meantime, the advantage of this API is that it makes it much less
awkward to use than the StringView variant when you have an
Optional<FlyString> namespace to pass through.
The original value 15 was too little: it made our
`weighted_boolean_fair_false` test fail every now and then.
This is because a fair coin (P(false) = 0.5) will hit the same value 15
times in a row with a probability (1/2)^15: around once in a 32k tries.
With the bumped up value, this is now once in 1 billion tries. Should
lower the test flakiness enough (if our random number generator is
truly uniform), while 30 tries is still an OK amount of computation for
randomized tests to do, compared to 15.
