Add Brick-to-AST Conversion Utility for Project Builder

[sruthin21]

This PR will resolve #399.

This pull request adds a new utility (blockToAST.ts) that converts the Project Builder’s IBrick objects into a simplified Abstract Syntax Tree (AST). Specifically:

Introduces a ASTNode class (or equivalent) for representing syntax elements.

Implements a convertBrickToAST function that maps each IBrick to an ASTNode, handling different brick types (data, expression, statement, block).

Includes a buildASTFromBricks function for converting multiple top-level bricks (e.g., each code stack) to an array of AST root nodes.

Provides placeholders and comments for handling child bricks, nested statements, and data values.

Adapts to the existing IBrick hierarchy (IBrickData, IBrickExpression, IBrickStatement, IBrickBlock) by casting as needed.
