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.

6e9eb0a284 LibJS: Add Object::get_without_side_effects()
Similar to Value::to_string_without_side_effects() this is mostly a
regular object property lookup, but with the guarantee that it will be
side-effect free, i.e. no accessors or native property functions will
be called. This is needed when we want to access user-controlled object
properties for debug logging, for example. The specific use case will be
error objects which will soon no longer have internal name/message
properties, so we need to guarantee that printing an error, which may
already be the result of an exception, won't blow up in our face :^)

ec62783af9 LibJS: Let Object::delete_property() return a bool, not Value
Just like the various define_property functions, this should return a
bool directly and let the caller deal with wrapping it in a Value, if
necessary.
