f8763c16b2 LibJS: Disable Temporal custom time zone test 
This test has been flaky for quite some time. Disable it for now, and
revisit once we've caught up with the Temporal spec.

96b197ef46 LibJS/Temporal: Perform floating point arithmetic in RoundTime 
The valid range for temporal values (`nsMinInstant`/`nsMaxInstant`)
means performing nanosecond-valued integers could lead to an overflow.

NB: Only the `roundingMode: "day"` case was affected, as all others were
already performing the division on floating-point `fractional_second`
values. I'm adding `.0` suffixes everywhere to make this fact clearer.

This adds a few local tests as well, as those are tested with sanitizers
enabled by default, unlike test262.

36ff6187f6 Everywhere: Change spelling of 'behaviour' to 'behavior' 
"The official project language is American English […]."
5d2e915623/CONTRIBUTING.md (L30)

Here's a short statistic of the occurrences of the word "behavio(u)r":

$ git grep -IPioh 'behaviou?r' | sort | uniq -c | sort -n
      2 BEHAVIOR
     24 Behaviour
     32 behaviour
    407 Behavior
    992 behavior

Therefore, it is clear that "behaviour" (56 occurrences) should be
regarded a typo, and "behavior" (1401 occurrences) should be preferred.

Note that The occurrences in LibJS are intentionally NOT changed,
because there are taken verbatim from the specification. Hence:

$ git grep -IPioh 'behaviou?r' | sort | uniq -c | sort -n
      2 BEHAVIOR
     10 behaviour
     24 Behaviour
    407 Behavior
   1014 behavior

cf0d30add6 LibJS: Add a function to ensure calls are made within the same second 
Before these tests could be flaky if they happened to be called around
the edge of a second. Now we try up to 5 times to execute the tests

392f5bfebd LibJS: Fix fraction substring range in parse_temporal_time_zone_string() 
Two issues:

- The intended range was 9 characters starting from index 1. Since the
  second argument to String::substring() is the length, 10 is
  potentially reading further than the string's length (when only
  providing one fraction digit), causing an assertion failure crash.
- The spec's intention to skip the decimal separator by starting at
  index 1 is incorrect, no decimal separator is present in the result of
  parsing TimeZoneUTCOffsetFractionalPart. I filed a spec fix for this,

027e4bd439 LibJS: Fix calculation overflow in parse_temporal_time_zone_string() 
As all variables and numeric literals in the expression have an integral
data type, it would evaluate to an int and could easily overflow as
we're multiplying seconds with 10^9.

Introduce a floating point literal into the expression to make it result
in a double.

f1276144ba LibJS: Check if input was exhausted after parsing UTC offset fraction 
Previously parse_time_zone_numeric_utc_offset_syntax() would return true
to indicate success when parsing a string with an invalid number of
digits in the fractional seconds part (e.g. 23:59:59.9999999999).
We need to check if the lexer has any characters remaining, and return
false if that's the case.
