Add Support for Array

[anfsity]

Feature Request: Array Support

Background:
This project requires adding support for one-dimensional arrays. The goal is to enable correct parsing and handling of arrays with multiply dimensions in the compiler, covering declaration, assignment, and element access.

Scope:

• Support parsing array declarations like int a[10];
• Ensure array element access works in expressions and statements
• Handle semantic checks related to array bounds and type safety

Approach:

• Update the grammar rules to allow multi-dimensional array syntax
• Update symbol table logic to store array information
• Make type checks for index expressions and assignments
• Implement code generation for array access
