[symbol table] use plain hash table to implement symbol table in isolate

The per-Isolate Symbol tables are implemented using NameDictionary
before, which has additional property details overhead
And NameDictionary is limited to 2^23, which limits the Symbol
tables to be a maximum of 2^23.

- replace NameDictionary with SymbolTable in isolate
