Andreas Kling f574ef528d LibJS: Replace Vector<Value> with Value* for named property storage 
Replace the 24-byte Vector<Value> m_storage with an 8-byte raw
Value* m_named_properties pointer, backed by a malloc'd allocation
with an inline capacity header.

Memory layout of the allocation:
  [u32 capacity] [u32 padding] [Value 0] [Value 1] ...
  m_named_properties points to Value 0.

This shrinks JS::Object from 64 to 48 bytes (on non-Windows
platforms) and removes one level of indirection for property access
in the asm interpreter, since the data pointer is now stored directly
on the object rather than inside a Vector's internal metadata.

Growth policy: max(4, max(needed, old_capacity * 2)).
