78cf6cde - [NFC][analyzer] Simplify ExprEngine::Visit, eliminate NodeBuilders (#200837)

[NFC][analyzer] Simplify ExprEngine::Visit, eliminate NodeBuilders (#200837) Remove NodeBuilder use from `ExprEngine::Visit` to reduce its size from 700 lines to 600 lines of source code. This commit also moves the "for instance method operators, make sure the 'this' argument has a valid region" logic (~10 lines) from the huge `ExprEngine::Visit` to the more specific `VisitCallExpr`; and applies a few other very minor code quality improvements.
