feat: add validation rules in `Memory` structure

[tcoratger]

Currently, there are two essential utility functions absent in the Memory structure that play a crucial role in validating memory. We need the following implementations in Ziglang:

A validateMemoryCell method

• Purpose: To validate a specific memory cell.
• Link to Rust Implementation: validate_memory_cell

A validateExistingMemory method

• Purpose: To validate the entire current memory based on predefined validation rules.
• Link to Rust Implementation: validate_existing_memory
