[Refactor] Add parser and formatter e2e testing

[colinthebomb1]

Overview:

This PR implements a basic e2e test for the parser and formatter, which compares the semantic equivalence of the original input query and output query

Code Changes:

• In tests\test_parser_formatter_e2e.py added test_basic_e2e() to run a basic e2e test with our parser and formatter, comparing the input and output using the mo_sql_parsing parse() function to ensure semantic equivalence.
