[code-reflection] RFR: Replace the use of Interpreter to create Quoted instance with specialized code [v12]

[Mourad Abbay]

> Creating Quoted instance was done by invoking the Interpreter. The Interpreter is too general and if someone could somehow inject any code model we will interpret that as well. This PR replace the use of the interpreter with specialized code.

Mourad Abbay has updated the pull request incrementally with two additional commits since the last revision:

 - Remove unused methods
 - Update QuotedHelper.makeQuoted to use CoreOp.quotedOp (that contains checks)
