New Light SQL Expression Parser

[tsutomi]

The current implementation of the SQL Expression parser makes use of ANTLR-generated that we want to make optional, and removed in Lite version

We need to define a new parser for SQL Expressions that is smaller in size (or even not define it if this is not possible)

[tsutomi]

The new model for parsing is delegating the parsing to implementations of ISqlExpressionParser contract: a default one is implemented using ANTLR4
