Andreas Kling c5427e5f4e LibJS: Convert Object bitfields to a flags byte ...

Replace individual bool bitfields in Object (m_is_extensible,
m_has_parameter_map, m_has_magical_length_property, etc.) with a
single u8 m_flags field and Flag:: constants.

This consolidates 8 scattered bitfields into one byte with explicit
bit positions, making them easy to access from generated assembly
code at a known offset. It also converts the virtual is_function()
and is_ecmascript_function_object() methods to flag-based checks,
avoiding virtual dispatch for these hot queries.

ProxyObject now explicitly clears the IsFunction flag in its
constructor when wrapping a non-callable target, instead of relying
on a virtual is_function() override.
