Add system-specific boot symbols and CPU instruction tests

Introduced symbol files for various Game Boy systems (CGB, AGB, MGB, SGB) to define boot sequences and functionalities. Included CPU instruction behavior tests, with detailed coverage of standard operations and interrupt handling. Added documentation for test execution and internal framework operations.
