Message:

Make global const initialisation explicit in the bytecode
​https://bugs.webkit.org/show_bug.cgi?id=96711

Reviewed by Gavin Barraclough.

Added op_init_global_const to make initialisation of global const
fields explicit. This will help us keep correct semantics in the
upcoming variable resolution refactoring.
