Andreas Kling f2df6b2531 LibJS: Add ClassBlueprint data structures
Introduce ClassBlueprint and ClassElementDescriptor structs that will
replace the AST-backed class construction path. ClassBlueprint stores
pre-compiled function data indices and element metadata, following the
same pattern as SharedFunctionInstanceData for NewFunction.

Add Vector<ClassBlueprint> to Executable for storage.

No behavioral change.
