[syntax-errors] Named expressions in decorators before Python 3.9 (#16386)
Summary -- This PR detects the relaxed grammar for decorators proposed in [PEP 614](https://peps.python.org/pep-0614/) on Python 3.8 and lower. The 3.8 grammar for decorators is [here](https://docs.python.org/3.8/reference/compound_stmts.html#grammar-token-decorators): ``` decorators ::= decorator+ decorator ::= "@" dotted_name ["(" [argument_list [","]] ")"] NEWLINE dotted_name ::= identifier ("." identifier)* ``` in contrast to the current grammar [here](https://docs.python.org/3/reference/compound_stmts.html#grammar-token-python-grammar-decorators) ``` decorators ::= decorator+ decorator ::= "@" assignment_expression NEWLINE assignment_expression ::= [identifier ":="] expression ``` Test Plan -- New inline parser tests.
