cd55b817cf LibJS: Use AK::abs in TimeZone 
This fixes a `-Wabsolute-value` warning emitted because of our use of
`abs()` on arguments of type `long long`.

b816037739 LibJS: Add the ToTemporalInstant Abstract Operation & its requirements 
This is Abstract Operation is required for the majority of
InstantConstructor's and InstantPrototype's methods.

The implementation is not entirely complete, (specifically 2 of the
underlying required abstract operations, ParseTemporalTimeZoneString
and ParseISODateTime are missing the required lexing, and as such are
TODO()-ed) but the majority of it is done.

a647f0abf6 LibJS: Make parse_simplified_iso8601() use Optional<int> instead of -1 
...for the non-success state. This fixes a crash when parsing dates with
the year -1, as we would assert successful parsing ("year != -1").
Mixing Optional and -1 seems worse and more complicated than just using
Optional for all the values, so I did that instead.

39cdffd78d LibJS: Make Date.now() return a floor()'d milliseconds value 
It is defined as follows:

    21.4.3.1 Date.now ( )
    https://tc39.es/ecma262/#sec-date.now

    The now function returns the time value designating the UTC date and
    time of the occurrence of the call to now.

"Time value" is defined as:

    21.4.1.1 Time Values and Time Range
    https://tc39.es/ecma262/#sec-time-values-and-time-range

    An ECMAScript time value is a Number, either a finite integral
    Number representing an instant in time to millisecond precision or
    NaN representing no specific instant.

By flooring the value we match the behavior in the Temporal proposal's
Temporal.ZonedDateTime.prototype.epochMilliseconds getter:

    4. Let ms be RoundTowardsZero(ℝ(ns) / 10^6).

With that being defined as:

    13.30 RoundTowardsZero ( x )
    https://tc39.es/proposal-temporal/#sec-temporal-roundtowardszero

    1. Return the mathematical value that is the same sign as x and
    whose magnitude is floor(abs(x)).

This is makes the last of the currently 15 Temporal tests in test262
work, which compares Temporal.now.instant() with Date.now() :^)
