PrimitiveString may currently only be created with a UTF-8 string, and
it transcodes on the fly when a UTF-16 string is needed. Allow creating
a PrimitiveString from a UTF-16 string to avoid unnecessary transcoding
when the caller only wants UTF-16.
Rather than deferring this decoding to PrimitiveString, we can decode
surrogate pairs when parsing the string. This prevents a string copy
when constructing the PrimitiveString.
Problem:
- New `all_of` implementation takes the entire container so the user
does not need to pass explicit begin/end iterators. This is unused
except is in tests.
Solution:
- Make use of the new and more user-friendly version where possible.
Problem:
- New `any_of` implementation takes the entire container so the user
does not need to pass explicit begin/end iterators. This is unused
except is in tests.

This commit adds the ZonedDateTime object itself, its constructor and
prototype (currently empty), and the CreateTemporalZonedDateTime
abstract operation.
Almost everything in LibJS includes Cell.h, don't force all code to
include AK/TypeCasts.h + AK/String.h. Instead include them where they
are actually used and required.
Evidently, going one day forward on the last day of month increases the
month number by one and resets the day to 1. Doing the same on the last
day of the year resets the month to 1.
The spec requires that invalid RegExp literals must cause a Syntax Error
before the JavaScript is executed. See:
https://tc39.es/ecma262/#sec-patterns-static-semantics-early-errors
This is explicitly tested in the RegExp/property-escapes test262 tests.
For example, see unsupported-property-Line_Break.js:
$DONOTEVALUATE();
/\p{Line_Break}/u;
That RegExp literal is invalid because Line_Break is not a supported
Unicode property. $DONOTEVALUATE() just throws an exception when it is
executed. The test expects that this file will fail to be parsed.
Note that RegExp patterns can still be parsed at execution time by way
of "new RegExp(...)".
