c2ebaa9d87 LibJS: Replace the verify in private identifier with a syntax error 
Since sometimes expressions are parsed without checking we can hit this
expression without it being followed by an 'in'.

b7c7d54167 LibJS: Split parsing program to script and module separately 
This allows us to only perform checks like export bindings existing only
for modules. Also this makes it easier to set strict and other state
variables with TemporaryChanges.

22174d3b7b LibJS: Rename in_async_function_context to await_expression_is_valid 
Since await can be valid in module code which is not an async function
the old name is not really representative for the usage.

045a42cf35 LibJS: Parse dynamic import calls 'import()' and 'import.meta' 
For now both just throw when executing but this can be implemented when
modules are implemented :^).

73eb29dabe LibJS: Lookahead for a period when parsing new.target 
This allows us to skip saving and loading the state whenever we parse
'new'.

cbbfcd35e7 LibJS: Disallow await keywords in static init blocks 
In static init blocks 'await' cannot be used. Note that this does not
cover all the cases since the parser currently cannot distinguish
between expressions within parenthesis and direct expressions.

c57721cf83 LibJS: Allow escaped 'async' as identifier 
Since 'async' is only special if it occurs before a function it can be
used as escaped identifier in all cases.

450dedabd1 LibJS: Add messages to the toEval and toEvalTo tests 
This makes it a lot easier to understand what is going wrong when an
eval test fails. As an example instead of just getting:
`ExpectationError`
You would now get:
`ExpectationError: Expected _1_2E+0_1_ to eval to _12_ but got _120_`.

75b2a09a2f LibJS: Implement a nearly empty Intl.DateTimeFormat object 
This adds plumbing for the Intl.DateTimeFormat object, constructor, and
prototype.

Note that unlike other Intl objects, the Intl.DateTimeFormat object has
a LibUnicode structure as a base. This is to prevent wild amounts of
code duplication between LibUnicode, Intl.DateTimeFormat, and other
not-yet-defined Intl structures, because there's 12 fields shared
between them.

914675e826 LibJS+LibUnicode: Separate number formatting methods from Locale.h 
Currently, we generate separate data files for locale and number format
related tables/methods, but provide public accessors for all of the data
in one Locale.h file. Rather than continuing this trend for date-time,
relative time, etc. formatting, it's a bit easier to reason about if the
public accessors are also in separate files.

bb11437792 LibJS: Change Intl's GetOption AO to accept a Span rather than a Vector 
Allocating a Vector for each of these invocations is a bit silly when
the values are basically all compile-time arrays. This AO is used even
more heavily by Intl.DateTimeFormat, so change it to accept a Span to
reduce its cost.

This also adds an overload to accept a fixed-size C-array so callers do
not have to be prefixed with AK::Array, i.e. this:

    get_option(..., AK::Array { "a"sv, "b"sv }, ...);

Reduces to:

    get_option(..., { "a"sv, "b"sv }, ...);

(Which is how all call sites were already written to construct a Vector
in place).

b3699029e2 LibJS: Implement the async versions of iterator operations 
Since AsyncIteratorClose and IteratorClose differ only in that the async
version awaits the inner value we just implement them with an enum flag
to switch just that behavior.
