There were two cases where tests in intl402/ had some duplication of tests
that are in built-ins/ as well. Remove this duplication, and restrict the
intl402/ tests to testing things that can't be tested on all hosts.
For cases in the previous commit that actually removed some functionality
from tests in built-ins/, add corresponding tests in intl402/ to preserve
test coverage of that functionality for hosts that do support Intl.
After Intl.NumberFormat v3, default useGrouping is "auto".
We also fix test/intl402/NumberFormat/test-option-useGrouping.js. After v3,
it accepts string and boolean.
We need to set minimumFractionDigits: 1 for the case of {roundingIncrement: 5, maximumFractionDigits: 1} and also adjust the test expectation.
Otherwise, inside testNumberFormat , it will call getPatternParts to format 1.1 and -1.1 and cause pattern mismatch (because the result will be "1" instead of "1.1" in that configuration)

The last five lines below are simply WRONG and not according to the spec.
```
const durationFormat = new Intl.DurationFormat();
verifyNotEnumerable(durationFormat, Symbol.toStringTag);
verifyNotWritable(durationFormat, Symbol.toStringTag);
verifyConfigurable(durationFormat, Symbol.toStringTag);
```
Move part of the test of toLocaleString which depends on
15 Amendments to the ECMAScript® 2021 Internationalization API Specification
to intl402. Keep behavior specified in earlier chapters in built-ins
* Add tests for "Intl NumberFormat v3" proposal
This patch is intended to cover only one aspect of the proposal for
ECMA402: the "interpret strings as decimals" feature.
* fixup! Add tests for "Intl NumberFormat v3" proposal
This patch is intended to cover only one aspect of the proposal for
ECMA402: the "grouping enum" feature. It also includes coverage for the
formatting option as already defined by the latest version of ECMA402.
Currently, this test is not conformant to the proposal text.
Temporal.TimeZone.from() calls ToTemporalTimeZone. Since the argument is
a string, we next go to ParseTemporalTimeZone, where on a string such as
`1994-11-05T08:15:30-05:00[UTC]` we would return _result_.[[Name]] (which
would be equal to `UTC`) and discard the UTC offset string.
Unfortunately, in #3304 I made a last-minute mistake when I added the
uncallable value to the assertion message, and neglected to test it;
Symbols can't be converted to strings like that, so these tests would
fail. This fixes the assertion messages.

In a previous version of the specification, there was a fallback to the
intrinsic getOffsetNanosecondsFor when it was undefined.
