Fix redeclaration related eval corner cases (#4886)

Browse Source 
- Fix cases where a function parameter binding is redeclared inside a parameter initializer eval
- Fix cases where a let- or function arguments binding is redeclared inside a function block because
  there is a declaration in a function parameter initializer eval
- Also remove the ECMA_PARSE_CHAIN_INDEX_SHIFT macro, added a debugger_eval_chain_index named field to the jerry context instead
