6c0d5163a1 LibJS: Add most of the Map.prototype methods 
Specifically all aside from "keys", "values" and "entries" which
require an implementation of the MapIterator object.

8d77a3297a LibJS: Improve Error/NativeError tests 
Some of this stuff is already tested properly in the name and message
prototype tests, so let's focus on covering all error types here as well
instead.

bc540de0af LibJS: Pass in actual_delete_count to removed array creation in splice 
More specifically, Array.prototype.splice. Additionally adds a missing
exception check to the array creation and a link to the spec.

Fixes create-non-array-invalid-len.js in the splice tests in test262.
This test timed out instead of throwing an "Invalid array length"
exception.

4bc98fd39f LibJS: Only "var" declarations go in the global object at program level 
"let" and "const" go in the lexical environment.

This fixes one part of #4001 (Lexically declared variables are mixed up
with global object properties)

2a3090d292 LibJS: Add the SetIterator built-in and Set.prototype.{values, entries} 
While this implementation should be complete it is based on HashTable's
iterator, which currently follows bucket-order instead of the required
insertion order. This can be simply fixed by replacing the underlying
HashTable member in Set with an enhanced one that maintains a linked
list in insertion order.

83be39c91a LibJS: Handle Proxy with Array target in IsArray() abstract operation 
This was missing from Value::is_array(), which is equivalent to the
spec's IsArray() abstract operation - it treats a Proxy value with an
Array target object as being an Array.
It can throw, so needs both the global object and an exception check
now.

e39dd65cf0 LibJS: Remove Proxy() argument count check 
Let's just treat missing arguments as undefined and throw with
'target/handler must be object' - this is more JavaScript-y.

59034554a4 LibJS: Account for differences in month representations (0-11 vs 1-12) 
Since DateTime stores months as 1 to 12, while JS accepts months as
0 to 11, we have to account for the difference (by subtracting or
adding 1) where appropriate.

d255e6892b LibJS: Update NumberPrototype's this_number_value() to take a Value 
This is now about as close to the spec as it gets - instead of querying
the |this| value inside of the function, we now pass it in from the
outside.
Also get rid of the oddly specific error messages, they're nice but
pretty inconsistent with most others. Let's prefer consistency and
simplicity for now.

Other than that, no functionality change.

c66b281856 LibJS: Fix functions binding this to global object in strict mode 
This fixes an issue where this would be bound to the global object
by default when operating in strict mode.

According to the specification, the expected value for |this| when
no binding is provided is undefined.
